順位はレビュー本文のスコア（100点満点）順です。★はApp Storeの評価です。評価について
Telegram remains one of the most fully featured messengers: fast sync, channels, and cloud storage all work reliably. But editing messages breaks the keyboard, and signing in without a phone number is still not possible.
評価点
Fast message delivery, a lightweight client, and regular updates with genuinely new features.
不満点
The editor covers the text with the keyboard, making it nearly impossible to fix a message in a channel.
向いている人：People who want a messenger with channels and file storage
Signal encrypts properly and holds up on privacy, but message delivery delays and inconsistent voice call quality come up regularly in reviews. It is not ready to be someone's only messenger.
評価点
Users trust the app enough to build local communities around it and treat it as infrastructure.
不満点
Messages often hang on 'Delivering' for several hours, and voice calls drop and sound unstable.
向いている人：People who value privacy over convenience
A rare tool for creating chat-format stories that kids and teenagers have used for years for fan fiction and roleplay scenes. The core mechanic works reliably, but gradual paywalling of previously free features like colors and avatars hurts the most active part of the audience.
評価点
The 'write a conversation' format offers an easy path into storytelling for people who do not like writing prose.
不満点
Basic character customization that used to be free is now behind a paywall, so stories all look the same.
向いている人：Teen fan fiction writers and fans of roleplay stories
A global messenger with end-to-end encryption that covers the basic need for internet-based communication. Its weak point is mass unjustified account bans with no real support path and reliability issues with video calls.
評価点：Works where there is no reliable cellular service and across borders without roaming charges.
不満点：The ban algorithm triggers on normal actions like messaging new contacts, and recovering an account is nearly impossible.
向いている人：People who communicate with friends or family abroad
Essential for staying in touch with Chinese relatives and colleagues, but registering without a contact already inside the platform is nearly impossible, and random account bans without explanation damage relationships with diaspora users. Calls and messaging are stable once you have an account.
評価点：Voice and video calls across borders work reliably and connect families in different countries.
不満点：Signing up requires scanning a QR code with someone else's account, which makes registration contingent on knowing the right person.
向いている人：Chinese people living abroad and their families
Marco Polo is an async video messenger for family and close friends: record a video, the other person watches when convenient. The core works, but captions have been moved behind a paywall, recordings sometimes cut off mid-message, and transcripts recently disappeared.
評価点：The video-voicemail format removes the pressure to reply immediately and keeps communication feel personal even across large time zone gaps.
不満点：Subtitles and transcripts have been moved to a paid subscription, cutting off deaf and hard-of-hearing users.
向いている人：Families and close friends who want to see each other's faces but live in different time zones
A messenger built on the Facebook network with good call and video quality. The main flaw is duplicate and delayed notifications, and a persistent Meta AI that cannot be turned off.
評価点：Video calls work cleanly and stably, connecting people across the world with no noticeable lag.
不満点：Read-message notifications repeat hours later, making it impossible to know what is actually new.
向いている人：Facebook users who want to call and message in one place
Apple's system messenger works as the default for anyone with an iPhone, but has accumulated real problems: texts 'teleport' between chats, group chat is capped at around 20 people, the sensitive content filter blocks harmless photos and interferes with calls. Message delivery reliability is questioned by a number of users.
評価点：Works without extra apps with any device including Android, and requires no registration.
不満点：The group chat participant limit and an unpredictable content filter that blocks normal photos and voice calls.
向いている人：iPhone owners who want one messenger for everything
A team messenger designed for educational institutions with a solid foundation, but email login breaks, crashes happen after updates, and notification granularity leaves something to be desired.
評価点：Quick group replies and video calls run smoothly.
不満点：There is no notification setting between 'all messages' and 'mentions only', so the phone buzzes all day.
向いている人：Students and work teams on institutional platforms
A solid tool for personalized mass SMS campaigns where each recipient sees an individual message. Sending speed is slow, support is hard to reach, and delivery reliability is inconsistent.
評価点：Each recipient gets a personal message rather than a group thread, which increases the chance of a reply.
不満点：Sending to a large group takes a long time, and each message requires a separate tap.
向いている人：Organizers, coaches, and small businesses who need personalized SMS broadcasts
Privacy without a phone number and E2E encryption work, but notifications arrive hours late, video calls are unstable, and the read receipt setting appears in the toggle but does not function. Not suitable for urgent communication, but adequate for low-key private chatting.
評価点：Registration with no phone number or email: just an identifier, no personal attachment.
不満点：Notifications about new messages arrive with delays of up to several hours.
向いている人：People who need maximum anonymity and can tolerate delivery delays
Zoom is the de facto standard for video conferencing in remote work and education. Call quality is stable on a decent connection, but joining a session through the mobile app periodically breaks and forces a switch to the browser.
評価点：Brings people from different time zones into one video session with no setup needed — just a link, and everyone is in.
不満点：Locking the phone screen during an active meeting ends the call without warning.
向いている人：Teams and study groups that need scheduled video meetings
A reliable option for video calls when FaceTime is unavailable or when cross-platform connectivity with Android users is needed. Picture quality is good, there are in-call games and drawing, but ads are intrusive and group calls perform worse than one-on-one.
評価点：Drawing on screen and mini-games during a video call make conversations feel alive.
不満点：Adult advertisements appear on a platform marketed for teen socializing.
向いている人：Children and teenagers staying in touch with friends and family
Discord handles organized communication for gaming and interest-based communities: servers, channels, voice rooms. The weak point on mobile is unreliable verification at login and frequent forced logouts.
評価点：Voice channels with no need to call — just join and talk until you leave.
不満点：The CAPTCHA at login freezes on a blank screen, and getting back into an account often requires switching devices.
向いている人：Gamers and online community members with persistent channels
A convenient Telegram client with additional features, but some are locked behind a paywall, ads are aggressive, and updates lag behind the official app. Without a VPN in Russia, stability is inconsistent.
評価点：Wide-format posts and extra customization tools on top of standard Telegram.
不満点：Updates arrive later than the official client, so new Telegram features do not appear right away.
向いている人：Telegram users who want extended customization
A good library of symbols and fonts for decorating messages, but the keyboard periodically stops appearing after updates, and the delete button sits too close to the working area.
評価点：A huge collection of symbols and non-standard fonts that are easy to paste into any messenger.
不満点：No undo button means accidentally deleted text is gone for good.
向いている人：People who decorate profiles and messages in games and social apps
ChatGPT is an AI assistant, not a messenger in the traditional sense: no message delivery between people, no groups, no contact sync. Response quality is uneven: strong on text and creative tasks, weak on precise facts and consistent memory.
評価点：Answers complex questions faster and in more detail than a search engine.
不満点：Memory is inconsistent: it remembers facts about the user but then mixes up contexts and requires repeated reminders.
向いている人：People who want an AI conversation partner for tasks, not a chat with other people
For internal work communication within Google Workspace it handles the job, but notifications drop out periodically, group chats require email invitations instead of simple adds, and Google Meet calls clutter the chat list with no way to remove them.
評価点：Cross-platform with no device lock-in, making it possible to message Android users where iMessage is unavailable.
不満点：Notifications regularly stop working and require reinstalling the app to restore them.
向いている人：Teams on Google Workspace who need a work chat
Messenger Kids solves a real problem: giving a child a safe chat under parental control with no access from strangers. But video calls freeze, group chats fail to create, and dependence on a parent's Facebook account becomes a blocker at any point of failure.
評価点：Children can message and call only contacts approved by a parent — no strangers.
不満点：Video calls freeze and drop in the middle, and the problem is easy to reproduce.
向いている人：Parents who want to give their child a messenger they can monitor
MySudo is strong as a privacy platform with multiple Sudos for different contexts, but incoming calls sometimes go straight to voicemail, message sync has delays, and support does not respond.
評価点：Multiple isolated numbers and email addresses in one app provide real control over your digital footprint.
不満点：Incoming calls regularly fail to ring and drop to voicemail without notifying the user.
向いている人：People who take their privacy seriously
ChatTales does one thing well: simulates a conversation between two people for storytelling and pranks. The two-character limit in the free version cuts off content creators right at the start.
評価点：A realistic iOS-style chat simulation that works well for short stories and pranks.
不満点：The free version does not allow a third participant, making group conversations unavailable.
向いている人：Text story creators and reaction video authors
For small offline communities like running clubs or interest groups it works well enough: events, chat, and members are all in one place. The main weakness is notifications that arrive late or not at all, and there is no search through message history, which is painful for an active group.
評価点：Combines an events calendar with a group chat in one tool without extra switching.
不満点：Notifications are unreliable, and there is no message search — very inconvenient in large groups.
向いている人：Organizers of offline communities: clubs, activity groups, interest meetups
MEGA stores files with zero-knowledge encryption and a generous free tier, but video playback regularly stalls due to bandwidth quotas and encryption latency, and losing the recovery key means permanent loss of access to the account.
評価点：End-to-end encryption and 20 GB of free storage with convenient file sharing.
不満点：Video streaming constantly buffers even on a fast connection due to server-side bandwidth limits.
向いている人：Anyone who needs a private storage solution with a large free quota
Call quality is good — audio and video work stably — but registration via SMS code often fails and blocks new users at the door.
評価点：Audio and video calls work without lag even on a poor connection.
不満点：The SMS verification code frequently does not arrive, and after several failed attempts the account gets locked.
向いている人：Users in Russia looking for a replacement for blocked messengers
Zoho Cliq integrates reasonably well with the Zoho ecosystem, but the mobile app is unstable: it crashes on older iPhones, logs itself out spontaneously, and drops notifications. That is not enough for reliable team communication.
評価点：Tight integration with other Zoho products means fewer browser tabs to juggle.
不満点：The app logs out on its own, causing notifications to disappear at the worst possible moment.
向いている人：Teams already working in Zoho One who need a built-in team chat
The idea of sending one message to a large contact list without creating a group thread is useful and workable. But as the list grows, sending speed drops sharply, the app hangs mid-broadcast, and updates periodically wipe contacts. Reliability is not enough for regular professional use.
評価点：Lets you send a personal message to hundreds of people individually rather than in a shared thread.
不満点：With large lists (300+ contacts) the broadcast stalls and will not complete without a manual restart.
向いている人：Event organizers and small businesses with regular mass broadcasts
The MagicJack VoIP app is stable enough for domestic voice calls, but suffers from system-level limitations: no MMS or photo support, spam calls reach the private number, and the call drops when the screen turns off. International calls are unreliable.
評価点：Lets you call US numbers from abroad as if it were a local call, with no roaming charges.
不満点：No way to send or receive photos or files — only text and voice.
向いている人：Americans who need a second number for calls without giving out their main one
The app works as a social network for young people, face verification filters out some fakes, but basic messaging features are hidden behind coins, match locations are global instead of local, and bans arrive without any clear reason.
評価点：Users genuinely meet and build relationships — several reviews describe couples who got together through the app.
不満点：Incoming messages and friend requests cannot be seen without payment, making connecting impossible without spending money.
向いている人：Teenagers and young adults up to 22 looking for new friends online
A live video chat app for strangers that worked better when it had a random matching feature, which was removed. Now calls drop after 10 to 30 seconds, coins are deducted during technical failures without refunds, and moderation fails to handle repeat offenders.
評価点：When video works stably, it genuinely connects users with real people and no bots.
不満点：Removing the random video call feature took away the main reason users chose this app.
向いている人：People who want live video conversations with strangers around shared interests
Basic messaging and calls work stably, but the forced ChatGPT integration with no way to disable it triggered widespread discontent and hurt the rating. The product is losing trust because of changes users never consented to.
評価点：Voice and video calls abroad work without notable interruptions, which users with family in other countries appreciate.
不満点：ChatGPT is embedded permanently in the chat feed and cannot be removed even through settings — the disable option does not work.
向いている人：Diaspora communities and families communicating across countries
Burner provides a real second number for calls and SMS and has served as a work line for years — that is genuine value. But the app takes 20 seconds to open, message history sometimes fails to load at all, and notifications do not arrive from unknown numbers.
評価点：A permanent second number that works for business calls without a second phone.
不満点：The app takes an unusually long time to launch — up to 20 seconds on a modern iPhone.
向いている人：Freelancers and small businesses who need a separate work number
Google Voice remains useful as a second number for call screening, but long-standing reliability issues have worsened: missed calls with no ring, failures when picking up, and Google silently reassigning numbers to other users without warning.
評価点：A permanent Google account number for registrations and as a screen for incoming calls.
不満点：Calls go to voicemail without ringing on the device, and the recipient has no idea.
向いている人：Google Workspace users who need a US number
A messenger for Korean audiences with rich customization and good photo quality, but largely unusable for users outside Korea: contact search does not work, ads appear directly in personal chats as fake messages, and constant verification prompts on login are annoying.
評価点：Photos are transferred without quality loss, and the profile can be customized in more detail than most messengers allow.
不満点：Ads are embedded in the personal message feed and are visually indistinguishable from real chats.
向いている人：People who communicate with Korean contacts or are learning Korean
The second number works for text messages in normal use, but calls frequently drop, photos disappear, and delivery reliability is questionable.
評価点：Getting multiple numbers in one app is convenient for separating personal and work contacts.
不満点：Calls consistently drop mid-conversation, making voice communication unreliable.
向いている人：People who need an anonymous number for text messaging only, without relying on calls
The inReach device itself works reliably as a satellite communicator, but the companion app is unintuitive, suffers from pairing failures, and requires an internet connection in places where the entire point is to work without one.
評価点：Reliable satellite communication in areas with no network coverage at all.
不満点：Some basic features require an internet connection, even though the device exists specifically to work without one.
向いている人：Hikers and travelers in areas without cellular coverage
This is essentially a browser with picture-in-picture, not a messenger. For background video playback it works reasonably well, but after updates X/Twitter stopped opening, links from other apps do not open, and there is no way to save a list of favorite URLs. As a communication tool it has almost no value.
評価点：Video from any website plays in PIP mode without ads and in the background.
不満点：No URL saving — you have to type the address manually every time.
向いている人：iPhone users who want to watch YouTube in the background without a subscription
A second number for texts is issued quickly and works in basic mode, but for some users it stops functioning after a few days and support only offers to unsubscribe. Suitable for one-off tasks, not ongoing use.
評価点：Instant delivery of a separate number without changing the SIM card.
不満点：Contacts disappear from the address book without any visible reason and cannot be recovered.
向いている人：People who want a separate number for marketplaces or dating apps
An anonymous SMS app that works stably for basic texts for some users, but for others messages never reach recipients — especially after payment. Support does not respond.
評価点：Lets you pick a number with a desired area code and start texting right away.
不満点：After activating a paid number, SMS delivery can stop entirely with no explanation.
向いている人：People who need a temporary anonymous number for one-off messaging
Text messaging works stably, but video calls drop constantly, audio echoes, and connection depends on the network. Fine as a text messenger, not as a video call tool.
評価点：A closed environment where children can message only adult contacts approved by a parent.
不満点：Video calls drop and freeze, making voice communication unreliable.
向いている人：Parents who want to give their child a safe messenger under their own control
The SMS conversation simulator for storytelling works as intended, but aggressive review prompts and a mandatory paywall from the first launch drive users away.
評価点：A realistic SMS dialogue interface lets you create engaging text stories.
不満点：Pop-ups asking for a rating interrupt the workflow right in the middle of creating a story.
向いている人：Teenagers who make text stories to share on social media
Microsoft Teams is a corporate platform for chat and calls that most users install on employer demand. The unread message counter is chronically wrong, sync between devices lags, and the app hijacks FaceTime calls.
評価点：For basic work chats and scheduled meetings it behaves predictably.
不満点：The unread badge does not reset correctly for months on end, making it impossible to navigate the message queue.
向いている人：Corporate Microsoft 365 users with no alternative
TextPlus provides a virtual number where no real one is available, and that is its core value. But messages get stuck on 'sent' with no delivery confirmation, calls drop without warning, and accounts are blocked unpredictably.
評価点：Works as a backup number for registrations and calls when a real SIM is unavailable.
不満点：Message delivery status does not update — a conversation can disappear until the app is restarted.
向いている人：Anyone who needs a one-time US number for verification
A collection of ready-made greetings and messages with a wide library, but text quality is uneven: many templates contain errors or sound generic. This is an inspiration tool, not a live messenger.
評価点：A large library of greetings for different occasions that is updated regularly.
不満点：Some templates are written with errors or use outdated phrasing.
向いている人：People who want a ready-made card or greeting without having to write one themselves
The WhatsApp Web wrapper works, but the session resets almost daily — which defeats the purpose of persistent access. Ads are aggressive and appear inside chats.
評価点：Lets you keep WhatsApp open on a device without the main account, which is handy for a second SIM.
不満点：The session drops on its own repeatedly, requiring the QR code to be scanned again and again.
向いている人：Users with two numbers or without the official WhatsApp app on their device
An OCR tool for copying text from the screen that works decently in typical scenarios, but handwritten text recognition is poor and accuracy dropped noticeably after updates. This app has no messaging features and is not a messenger.
評価点：Recognizes printed text from photos accurately enough and requires no complex setup.
不満点：Handwritten text is recognized with errors, and OCR quality has declined after updates.
向いている人：Anyone who needs to quickly copy text from a photo or screenshot
WhatsApp Business adds a business profile, catalog, and auto-replies on top of regular WhatsApp, but after several updates the app stopped launching reliably on older iPhones and suppresses the busy-line notification during an incoming call.
評価点：A business profile with a catalog and quick replies reduces routine when working with customers through WhatsApp.
不満点：The app does not show a 'busy' status to callers, so clients call again and again while interrupting an ongoing conversation.
向いている人：Small businesses whose audience is already on WhatsApp
An anonymous SMS service that works for simple texts, but cannot send photos, limits message length, and requires credits even for basic actions.
評価点：Sending messages without linking a real number covers the need for anonymity.
不満点：Attachments and long texts are unavailable without a paid plan, which breaks normal conversation.
向いている人：Anyone who needs to send an anonymous message once and does not expect a photo reply
Talkatone provides a free Wi-Fi number, but message delivery reliability is inconsistent: outgoing messages are flagged as 'spam' during normal conversations, verification codes do not arrive, and support is effectively unavailable.
評価点：Easy to get a number without personal data and start calling for free.
不満点：The anti-spam system blocks outgoing messages if you send several in a row during a normal exchange.
向いている人：Anyone who needs a free Wi-Fi number for calls in the US without a real SIM
Positioned as a TikTok alternative for older audiences, but basic messenger features break regularly: messages do not send, live stream notifications disappear, and new accounts become invisible to other users.
評価点：A platform without heavy moderation gives a sense of free expression for older audiences.
不満点：The content feed algorithm is unpredictable and pays little attention to the user's language and interests.
向いている人：Content creators looking for a TikTok alternative
Snapchat is a messenger with disappearing messages and AR filters, but its core — snap delivery — breaks regularly: videos do not display, notifications ignore disabled categories, and sessions crash. The product is degrading under monetization pressure.
評価点：Disappearing messages and AR lenses still make communication feel visually alive.
不満点：Notifications ignore user settings and push filter ads regardless.
向いている人：Teenagers who communicate through images rather than text
A spam message blocker that worked well for the first few months, then degraded: it lets spam through, blocks important messages from pharmacies and doctors, and does not work on Mac or iPad.
評価点：At its best the filter genuinely brings spam down to zero with no manual configuration.
不満点：The filter loses precision after updates and starts blocking legitimate messages from real senders.
向いている人：iPhone users willing to tolerate instability in exchange for a quiet period with no spam
The mass SMS app used to work for years, but after recent updates it reliably sends messages to only part of the recipient list. Support is silent. The core feature is broken.
評価点：Used to let organizers send a personal SMS to hundreds of contacts in one tap without a group thread.
不満点：After updates, the message only goes to the last contact added, not the full group.
向いている人：Church community and club organizers who need mass SMS broadcasts
The app is positioned as a messenger for international video calls, but basic problems have gone unsolved for years: the call automatically drops after 5 minutes, audio does not switch to AirPods without hanging up and calling back, and messages appear out of chronological order. Group video calls are absent.
評価点：Users in the UAE note stable video quality where other apps are blocked.
不満点：Calls drop automatically after 5 minutes, and audio through headphones does not switch without hanging up.
向いている人：Users in countries with restricted access to WhatsApp and FaceTime
Basic SMS delivery works adequately, but calls are interrupted by ads mid-conversation, spam calls target even paying users, and support is unreachable. The product is unreliable as a primary communication channel.
評価点：Quick setup of a second number and eSIM activation without visiting a store.
不満点：Spam calls are not blocked even on the paid plan, making it hard to tell a real contact from a robot.
向いている人：Anyone who needs a temporary number for a one-time registration
An app for random voice encounters that suffers from poor call quality, aggressive and inappropriate content, and opaque account bans.
評価点：Live calls with strangers from different countries provide a sense of real human connection.
不満点：Moderation cannot keep up with sexual content and scammers, and the atmosphere deteriorates quickly.
向いている人：People who want to talk to a stranger right now
BFF fails at the basics: messages do not send, sessions crash, and phone verification works intermittently. The interest-group concept is solid, but the audience is too small to feel it.
評価点：Interest-based groups genuinely ease the first contact and remove the awkwardness of a one-on-one.
不満点：Messages stall or do not arrive, especially after a session break.
向いている人：People looking for offline friends who are willing to put up with instability
The app bans well-behaved users due to errors in the automated verification system and does not respond to appeals, while continuing to charge for subscriptions. The core dating and messaging function is unreliable.
評価点：Mandatory face verification reduces the number of fakes compared to similar apps.
不満点：The automated ban triggers at registration without any violation, and there is no way to appeal through support.
向いている人：Young people looking for friends through short video introductions
Messenger Multi Business is an unofficial WhatsApp client for iPad and multi-account use that requires constant re-syncing while retaining access to the user's account. Sync drops daily, QR codes are flagged as invalid, and video calls have poor audio.
評価点：The free version provides the main WhatsApp features with only a single banner at the bottom of the screen.
不満点：The session drops every day and requires scanning the QR code again, which defeats the whole idea of multi-device access.
向いている人：iPad owners who need WhatsApp without a second phone nearby
A virtual number for calls and texts that is unreliable: audio is quiet or muffled, message notifications drop, and accounts are blocked without warning. Reliability is at the level of a backup number, not a primary one.
評価点：Quick setup of a second number for separating personal and work contacts.
不満点：Calls frequently drop or sound muffled underwater, making them unsuitable for business conversations.
向いている人：Anyone who needs a temporary backup number
This is not a messenger but a catalog of ready-made phrases and quotes to forward on WhatsApp. It works as a utility: copy text and send. But ads insert a download link into copied text, which annoys recipients.
評価点：A large library of ready-made messages for holidays and occasions — no writing required.
不満点：When copying text, the app automatically appends an ad link to the app download page.
向いている人：People who regularly congratulate loved ones and do not want to write something each time
The social chat for meeting people has deteriorated: moderation stopped working, content has become coarser, and users receive permanent bans without explanation or any way to appeal.
評価点：At launch the app created a live community where people genuinely answered questions and made connections.
不満点：The ban system is opaque and inconsistent: well-behaved users are blocked while actual violators keep using the app.
向いている人：Teenagers over 16 looking for casual conversation, if they can tolerate chaotic moderation
The app offers a collection of notification sounds, but installing a chosen tone on iPhone without iTunes is extremely difficult, and the custom tone creation feature may not work after payment.
評価点：A large library of non-standard sounds that are not available in the default iOS set.
不満点：Setting a tone on the device requires iTunes and several manual steps, which puts most users off.
向いている人：iPhone users willing to deal with iTunes for a non-standard notification sound
GroupMe holds on in the niche of group chats for schools and teams, but basic features are broken: messages get lost in open chats, pins disappeared after an update, and logging in becomes a cycle of password resets.
評価点：Group chats work across mobile platforms, which is convenient for mixed-platform teams.
不満点：Messages regularly get lost even when the chat is open and active — which undermines the entire point of reliable group communication.
向いている人：School and sports groups stuck on this platform
The app lost its audience after the pandemic and now suffers from intrusive notifications, a broken in-room chat, and a creator reward program that does not pay what it promises. It is no longer reliable as a communication tool.
評価点：Those who stayed have found a close community and spend up to 14 hours a day in rooms.
不満点：The chat inside an active room does not show new messages until you leave and rejoin.
向いている人：Audio fans who joined back in 2020 and never left
Bigo Live is a streaming platform with chat and virtual gifts, not a full messenger. Bans arrive without explanation and can last up to a year, moderation is inconsistent, and private messages are rife with scam schemes.
評価点：Streamers appreciate the live audience and the gifting system, which actually works.
不満点：The matching algorithm ignores gender and orientation settings and shows irrelevant people.
向いている人：Mobile streamers who want a live audience with donation support
A second number with opaque pricing: users report unexpected charges during the 'free' period, message history disappears, and settings are glitchy.
評価点：The idea of a separate number for work contacts without a second SIM is convenient.
不満点：Messages disappear and message history is not retained, making the app unreliable.
向いている人：Not recommended for anyone in its current state
A social walkie-talkie for random conversations around the world, but recent updates removed key modes and broke basic channel navigation. Long-time users are leaving precisely because the app stopped being itself.
評価点：The atmosphere of random voice encounters and the feel of a live radio broadcast.
不満点：Duet conversations and frequency shuffling — the mechanics that drove discovery — have been removed.
向いている人：Fans of voice chats with strangers
LINE is losing users in the US because login without an old device is impossible and phone number registration is blocked. Media delivery is unreliable even for existing users.
評価点：Stickers and the app's atmosphere work well within the Japanese market.
不満点：Transferring an account to a new device is virtually impossible without simultaneous access to the old one.
向いている人：Users in Japan and Asia who have been on the same device for a long time
Blink is positioned as a friend-finding app, but phone number verification breaks, fake and potentially unsafe profiles appear frequently, and core features work unpredictably.
評価点：The concept of quickly meeting compatible people without a romantic framing appeals to part of the audience.
不満点：Phone verification fails regularly, blocking new users from getting in.
向いている人：Teenagers and young adults looking for new friends online
The app was built on privacy trust but has degraded: notifications are broken, sending photos and videos does not work, and copy-paste was removed in an update. The core messenger function — reliable delivery and notifications — is not working.
評価点：Messages disappear after 24 hours without any configuration, anonymously and with no extra steps.
不満点：Notifications for incoming messages arrive inconsistently or not at all.
向いている人：People who want an anonymous ephemeral chat and can accept limited functionality
Messages get stuck on 'sending', incoming images do not arrive, calls drop, and accounts are blocked without warning or any path to appeal. The product is unreliable as a communication channel.
評価点：Works as a backup number when you need to reach someone who has blocked your main contact.
不満点：The spam algorithm blocks conversations with real people, including family members, without explanation.
向いている人：People who want to hide their real number from a specific contact
The app is positioned as a way to run a second WhatsApp on iPad, but it is essentially just a browser wrapper opening web.whatsapp.com. Message sync breaks after updates, and users who realize what they actually bought feel misled.
評価点：For anyone who needs a second WhatsApp account on the same device, the concept works.
不満点：After updates, sync with the main WhatsApp breaks and messages stop loading.
向いている人：iPad users with two WhatsApp numbers who need quick access from a tablet
A social messenger for dating where ads literally cover interface buttons and make the chat inaccessible without a paid subscription. Live streaming was removed from the app entirely. Message sending is unreliable.
評価点：Over years of operation it has gathered a real community of regular users who have been there a long time.
不満点：Ad banners cover the bottom navigation menu and make it impossible to tap the chat buttons.
向いている人：Users who registered long ago and came for a specific social circle
Calls drop after an hour, ads redirect to potentially harmful pages, incoming call notifications do not trigger, and registration often hits an error wall. The product does not reliably perform basic functions.
評価点：For tablets without a SIM card it is one of the few ways to text Android contacts.
不満点：Incoming calls go straight to voicemail with no chance for the user to answer.
向いている人：Tablet owners without a SIM who need some kind of number
The messenger breaks regularly after updates and crashes when switching between apps. Media delivery is unreliable. Using it for work is risky.
評価点：When it is working stably, the interface resembles familiar messengers and requires no learning curve.
不満点：The app crashes every time it enters the background and hangs after updates.
向いている人：Users who need private messaging without linking a phone number
Azar started as a random video chat for meeting strangers, but a new update replaced random matches with gem-based invites. Users are demanding a rollback en masse, credits are deducted without connections being made, and there is no way to search by username.
評価点：The idea of a random video chat with people from around the world was alive and worked before the update.
不満点：There is no way to find someone by username — only a random match or invite — making reconnection impossible.
向いている人：People who want to video chat with strangers from other countries
An anonymous communication app where the core feature of sending messages periodically stops working after updates. Notifications do not lead to the right chat, and content moderation is nearly absent. Much of the audience has been inactive for years.
評価点：An anonymous profile allows communication without any attachment to a real identity.
不満点：Messages stall on sending indefinitely, and new chat notifications do not open the right conversation.
向いている人：People looking for anonymous communication with strangers without revealing their identity
評価点：At one point it offered live video introductions with real people.
不満点：Matches have become pre-recorded videos rather than a live stream.
向いている人：Not recommended for anyone in its current state
The app is positioned as a shortcut for messaging on WhatsApp without saving a contact, but basic features do not work: devices keep disconnecting, the QR code must be scanned every time, and phone numbers are not recognized. This is not a messenger — it is a wrapper that breaks on first real use.
評価点：The idea of opening a chat with an unknown number in one tap is convenient for businesses and services.
不満点：The device connection drops constantly and requires re-linking via QR code.
向いている人：Small businesses that need quick chats without saving contacts
After updates call quality dropped sharply: missed calls do not appear in notifications, OTP codes do not arrive on re-login, and group calls have no audio. The app is unstable for regular communication.
評価点：Works in the UAE where other messengers are blocked.
不満点：Incoming calls do not appear in phone notifications unless the app is opened manually.
向いている人：Users in countries with VoIP call restrictions
An anonymous-chat social app for meeting people that suffers from slow media loading, freezes on re-login, and a complete absence of audience filtering. Video sending is so slow that users assume the feature is broken. The quality of interaction depends on the audience makeup — and it is inconsistent here.
評価点：There is a live audience from different countries, and some conversations genuinely take off.
不満点：Video does not send properly, and the app freezes on re-login via Google.
向いている人：People looking for casual chat with strangers around the world
The app positions itself as a Wi-Fi call and text tool, but incoming texts disappear from the interface, incoming calls interrupt and drop the current call, and verification codes from third-party services never arrive. The core use case does not work.
評価点：The concept works on paper: a second number via Wi-Fi without a physical SIM card.
不満点：Received messages disappear from history with no trace of delivery.
向いている人：Anyone who needs a second number for Wi-Fi calls — if they can find a working alternative
SayHi is overrun by scammers and fake accounts, voice calls do not work for some users, and a points system restricts communication. Finding a genuine conversation partner is difficult.
評価点：There are real users from different countries, and some of them genuinely want to connect.
不満点：Moderation cannot handle the volume of scammers and extortionists, which poisons the entire experience.
向いている人：People looking for language exchange partners who are willing to filter out scammers themselves
A VoIP call and SMS app with a virtual number where text messages consistently fail to reach recipients, calls drop due to network issues, and you can only manage a group you created yourself. Support does not respond for months.
評価点：The approach works for privacy: a separate number with no SIM card attachment.
不満点：You cannot join a group created by another user — only your own.
向いている人：Not recommended for anyone in its current state
A virtual phone number app for calls and SMS that issues a number but after payment calling does not actually work: no dial tone, SMS do not arrive, verification codes never come through. The payment structure is confusing — a subscription does not include minutes, you have to buy coins separately.
評価点：The need for a second number without a SIM is real, and occasionally after a long wait calls do go through.
不満点：After payment, calls and SMS often do not work at all and verification codes do not arrive.
向いている人：Users who need a temporary second number for verification
The app consistently fails to deliver SMS and calls after activation: numerous reviews document the same thing — messages do not reach sender or recipient, credits are spent with nothing sent, and support does not respond. The core virtual number feature does not work.
評価点：The ability to choose a number from a list at registration is a convenient and clear experience.
不満点：SMS do not reach the recipient even with an active balance and a working connection.
Messages do not arrive, assigned phone numbers are lost while the subscription is active, and support does not respond. The virtual number as a product does not work.
評価点：The idea of getting a separate number for different tasks is clear and in demand.
不満点：The assigned number can disappear at any moment without warning.
向いている人：Not recommended
The app promises to turn chat screenshots into formatted stickers, but almost all functionality is behind a paywall from the very first message. There is no real value as a communication tool — this is customization for its own sake with a minimal free tier.
評価点：The idea of overlaying a styled sticker on top of a real message looks visually interesting.
不満点：Stickers do not fit over other people's messages well: the scale is off and the orientation is wrong.
向いている人：Teenagers who want to decorate chat screenshots
The chat feed hangs and shows 'loading' indefinitely, streams crash every 4 to 5 minutes, face verification does not work, and the majority of profiles are bots or scammers. The product is broken across all key functions.
評価点：Streamers receive a higher share of gift revenue than on large platforms.
不満点：Opening the incoming message list is impossible — the app freezes on loading.
向いている人：Streamers for whom gift monetization matters more than reach
The app is positioned as an SMS replacement, but it only works within its own network. Writing to anyone in your regular contacts is impossible unless they also install this messenger.
評価点：The interface looks like a standard calls-and-messages app.
不満点：Communication with numbers outside the app does not work, even though that is exactly what the description promises.
向いている人：Not recommended
Litstick is a sticker overlay for pranks, not a messenger: it creates a fake-chat image to place over a screenshot. Most users do not understand how it works, the sticker does not match the chat bubble size, and the vast majority of reviews express disappointment.
評価点：The idea appealed to people who wanted to prank their friends.
不満点：The sticker overlay does not scale to actual message bubbles, so the result always looks fake.
向いている人：Teenagers who want to fake a chat screenshot for a prank
The app is positioned as a dating service, but the overwhelming majority of active profiles are described by male users as bots or people requesting money. Genuine meetings are rare, chat is unstable, and the like algorithm is opaque.
評価点：A handful of real users did find connections, which shows the concept can work.
不満点：There is no way to tell a live profile from a bot without paying to reveal a match.
向いている人：Not recommended in its current state
評価点：Technically the basic chat features work correctly.
向いている人：Not recommended
The app is filled with bots posing as real people: the same phrases, conversations that drop after two messages, and AI avatars. There is no real communication.
評価点：Some users find it useful for killing time in a one-sided way.
不満点：Nearly all conversation partners are bots or fake profiles — genuine interaction does not happen.
向いている人：Not recommended
