In the reviews, context and settings that survive are what matter. What helps is a personal dictionary, a comparison of options and an original that stays available for checking.
The best text translator in this batch for accuracy, which users with professional language knowledge confirm. Camera works but is slow (about 5 seconds per frame). Voice synthesis sounds dated. The app stopped remembering the language pair between sessions after one update.
評価点：Translation accuracy when handling nuance: alternative phrasings, gender agreement, and register are all taken into account.
不満点：After every launch the app resets the language pair to the default and does not remember your preference.
向いている人：People who translate carefully and care about precise wording rather than speed.
A full-featured translator with text, voice, and a keyboard extension. Covers over 100 languages. Relevant for the category.
評価点：The built-in keyboard lets you translate right inside WhatsApp and other messengers without switching apps. Listening to pronunciation helps you both understand and reproduce a word.
不満点：Translation quality is inconsistent across languages: Italian works better than French, and Greek transliteration contains errors. Voice translation occasionally produces wrong phrases without any warning.
向いている人：Travelers and people who regularly message with foreign contacts and want to translate without leaving the chat.
A translator keyboard that plugs into any app and translates as you type. A genuinely useful idea. But the $10-per-week price kills any goodwill: it is more expensive than most premium translators on the market.
評価点：The built-in keyboard works in any messenger without switching apps. Translation right in the input field is a mechanic without a real equivalent among most competitors.
不満点：The keyboard runs noticeably slower than the default. Translation quality drops for languages beyond Spanish. Security concern: the keyboard requires 'full access,' which means it can potentially read anything you type.
向いている人：Someone who regularly writes in two languages in messengers and is willing to pay for speed. At $10 a week that is a very narrow audience.
Works as an overlay translator directly over WhatsApp and Instagram without switching apps. Built-in grammar check with multiple suggestions. Word list and personal dictionary mode. Weak spots: long messages get cut off, no full-screen support on iPad.
評価点：Overlay mode: translate text in any app without copying or leaving. Multiple translation engines in a single interface.
不満点：Long texts do not display in full. Grammar check does not show a correction when there is only one error.
向いている人：Users who message in social apps in a foreign language and want to translate right inside the chat without switching apps.
A translator with text, voice, camera, and AI features. Technically well-equipped, but monetization is aggressive: $10 a week for most features. The store reputation does not match the real user experience.
評価点：ChatGPT integration delivers more contextual translations of phrases and idioms where classic engines give a literal result. The keyboard extension works for free.
不満点：Most features (camera, live translation, voice) are locked without a subscription, and this is not explained before install. Connection errors on live translation reproduce even on a solid internet connection.
向いている人：A user who needs fast text translation and is willing to pay for full AI feature access with full price transparency up front.
