Best period tracker apps

Specialized PMDD tracking with dedicated tools for working through symptoms as they happen, not just logging them. European data jurisdiction is especially valued in this category. Provides science-backed information on hormones and explains the connection to symptoms.

You cannot edit symptom entries after closing the day, so correcting past data is impossible. Daily goal settings cannot be saved as a template and must be re-entered each time. The symptom list is fixed with no option to add custom categories.

Women diagnosed with PMDD or suspected to have it, and those who have come off hormonal contraceptives and want to understand their cycle deeply. Not for those who only need a period date prediction.

Works with PCOS and irregular cycles: the forecast adapts to symptoms and stress rather than just averaging past data. Detailed log covering symptoms, mood, sleep, and weight. Full pregnancy mode with a smooth transition that preserves history.

Data transfer when switching devices raises concerns for some users, with documented cases of lost history. Tag search in the journal does not work. Data from older entries sometimes syncs incorrectly from the Health app.

Women with irregular cycles or PCOS, or anyone who wants a full-featured tracker without a mandatory subscription.

Automatic scanning and digitizing of test strips into a numerical value removes guessing from line shading. Several users with PCOS say Pregmate was the first tool that helped them catch their unstable LH peak.

After confirming pregnancy, the app does not offer pregnancy tracking, which users only find out after the fact. The period prediction algorithm sometimes keeps pushing the date forward instead of acknowledging a missed estimate.

A woman trying to conceive who uses ovulation test strips and wants to remove subjectivity from reading results while seeing LH dynamics across the cycle.

Real temperature analysis with confirmed ovulation detection, comparison against a database of real charts, thorough educational content, and support for cycles of 30 to 70-plus days.

The interface looks visually dated. The forum can be toxic. TTA (avoiding pregnancy) features are weaker than the TTC ones.

Those who want to truly understand their cycle through the temperature method, especially with PCOS or long and irregular cycles.

Photo recognition of LH strips turns a test strip into a numerical graph where you can see the peak and its dynamics. Works with PCOS involving long and irregular cycles. Several specific conception stories after years of unsuccessful attempts.

Long cycles with PCOS (60-plus days) are sometimes interpreted incorrectly. Phrasing in the app around 'your fertility' and weight advice comes across as tone-deaf. Not suitable for IVF or IUI scenarios.

Women actively TTC, including those with PCOS, who are willing to use test strips and want to see biomarkers rather than just calendar predictions.

Accuracy for irregular cycles: users with ADHD and chronic conditions say Cycles was the first app to consistently predict their unstable rhythm. The countdown widget to the next cycle changes how they plan. Color-coded phases are clear without extra text.

The partner mode syncs unreliably: data logged by one partner is not always visible to the other. The mood and symptom vocabulary is basic and does not always reflect real experience. You cannot select individual modules without getting access to the whole package.

Women of any age who want a reliable, unobtrusive tracker without extra noise: a long-term cycle journal without gamification or content feeds.

All symptoms are visible as icons directly on the monthly view: a unique feature among this type of tracker and essential for pattern analysis. History going back to 2012 is accessible and readable. Successfully used for avoiding and planning pregnancy based on reviews with specific results.

The 2024 redesign made navigation harder with options placed less intuitively. Apple Health integration on iPhone is weaker than users expect from a mature app. Additional access tiers have been layered on top of previously purchased features, effectively trimming functions users already paid for.

Users willing to pay a one-time fee for a detailed journal without ads, who track data over years and do not rely on Apple Health ecosystem integration.

Fast input: mark the start of a cycle and the forecast is ready, with no extra screens. Works with PCOS and irregular cycles, including after IUD placement. Customizable reminders and a countdown widget.

With an irregular cycle, it sometimes shows a delay without explaining why or adapting the algorithm. Accuracy in the first months after giving birth is low. You cannot add a non-standard contraceptive type to track.

Women who want a fast, honest cycle tracker without a subscription, including those with PCOS.

Daily cycle-phase advice is written in a supportive tone: users compare it to guidance from an older sister rather than medical instructions. Symptom and mood history shown as icons on the monthly view without clicking into each date.

The interface is overloaded with sections, making it harder than it should be to get to simple period entry. The automatic end-of-cycle date entry is sometimes incorrect and needs manual correction. Medication reminders arrive in the morning even when the record was entered in the evening.

Those who want more than just a calendar and care about understanding their body through their cycle, with an emphasis on a caring tone rather than medical monitoring.

Content explains cycle physiology in language free of medical jargon and anxiety. Customizable symptom buttons expanded from a minimal set to a wider one over years of development. The discreet icon and name do not reveal the app's purpose to others.

Prediction accuracy for irregular early cycles is low: the app warns about this but does not adapt the algorithm quickly. The vocabulary for describing flow intensity is limited. For users over 16, the interface can feel young.

Girls aged 10 to 16 with early or irregular cycles who need a gentle starting point without adult-oriented content.

Enables parallel tracking of the menstrual cycle, chronic conditions, medications, and mood: the only tool that shows correlations across all patterns. A strong tool for preparing for doctor visits, since doctors receive concrete data rather than a recollection from memory.

Adding a one-off symptom became more steps after a format update. Sleep tracking has been added but works less reliably than dedicated apps. The learning curve is steeper than a typical cycle tracker.

People with chronic conditions who want to see how their cycle interacts with pain, energy, mood, and other symptoms in one place.

Neutral design without mandatory pink tones: users choose the color themselves. Apple Health sync pulls in history automatically without manual entry. The discreet icon does not attract attention.

Data from the Period app does not fully sync back into Apple Health. There is no way to exclude pregnancy or lactation periods from the average cycle calculation. The algorithm does not recalculate its model when predicting after a long gap.

Those who need a simple, ad-free tracker with no reproductive agenda for monthly monitoring. Works well for teens and those who value privacy.

Full functionality in the base version: cycle tracking, cervical mucus, and basal temperature in one app. Accumulated history of 94 or more cycles stays intact and readable. Long-term users report accurate cycle predictions based on established patterns.

The learning curve is steeper than a standard tracker: the mucus tracking methodology requires reading through instructions. Early predictions based on a single day of data give unreliable results. After a May 2024 update, some users experienced breakage of core functions.

Those practicing the sympto-thermal method who want free in-depth analytics and are aware of the app's ideological background.

The only tracker in the set that reads test strip photos and converts them to numerical data. Ovulation prediction based on real biomarkers, not just dates. Helped users with PCOS conceive after many months of trying.

Long PCOS cycles are not handled correctly. Some health tips come across as offensive (body shaming). The accessory ring does not always sync.

Women actively planning a pregnancy who are willing to use test strips or a temperature sensor.

Prediction accuracy for irregular cycles ranging from 27 to 48 days, with several specific confirmations. No push notifications and no unnecessary questions. Customizable themes and simple data entry.

Documented data sharing with 59 third-party trackers, discovered via the iPhone Privacy Report. Some symptoms are hidden behind additional access and only return after a version update. No built-in symptom pattern analysis.

Those who want an accurate, quiet tracker for irregular cycles without aggressive notifications, but are willing to accept a privacy trade-off.

Customizable symptom fields: you can track any parameter not covered by standard trackers. Daily motivational quotes get mentioned surprisingly often as a pleasant detail.

Several past updates reset data without warning. The home screen in the new version shows a lot of clutter and some users cannot find the main cycle ring view. Pregnancy and postpartum tracking are not included.

Women aged 25 to 45 with unusual symptoms or conditions like PCOS, copper IUDs, or heavy flow who need a flexible journal without forced categories.

Real hormone numbers instead of guesswork. Especially valuable with PCOS. Visual graph of four hormones across the cycle.

No Apple Health sync. The app does not explain hormone values. The peak is sometimes missed with first-morning urine samples. Testing takes 10 minutes with the phone in hand.

Those who have tried every tracker and every LH strip but still cannot understand what is happening with their cycle, especially with PCOS or after treatment.

Visually neutral: a numerical countdown widget does not attract attention and does not reveal its purpose to someone looking at another person's screen. Accurate forecast for regular cycles. Simplest possible input: one tap to mark the start.

No contraceptive tracking beyond the pill, so users on other methods cannot log them. The fertile window does not adapt to non-standard cycles. Very basic symptom set with no option to expand.

Those who only need a day counter with nothing extra: teens, non-binary users, people with regular cycles who do not want to share health data.

A llama that reacts to symptoms and mood: a concrete daily return mechanic without forcing anything. A countdown widget to the next period. A supportive tone, free of shame and excessive medical anxiety.

Accuracy for irregular cycles takes several months of learning to develop, which is not always clear at first launch. Most symptom and journal features are behind a paywall, and the audience is predominantly minors without a payment card.

A teenage girl aged 12 to 17 just getting started with cycle tracking and needing a friendly, low-pressure entry point.

No forced registration and data is stored locally. Accuracy for irregular cycles improves with length of use. Detailed journal with icons for symptoms, moods, and intimate days. Landscape mode.

The ovulation date is calculated automatically and cannot be corrected manually. Reinstalling without a backup means losing all data. The interface has not been updated in years and looks dated.

Those who want a reliable local tracker with no account, are fine with a minimalist design, and value long-term prediction accuracy.

Rich customizable journal: custom mood icons, detailed notes, and years of history. Cycle accuracy accumulates over time, with veteran users saying the app hits the day almost every time. Helps with PCOS diagnosis by revealing patterns over extended periods.

Ovulation day and fertile window predictions are specifically criticized: several reviews mention unintended pregnancies due to incorrect dates. Loss of 10 years of data has been documented.

Those who want a detailed personal cycle and symptom journal without a strict focus on conception.

Broad symptom list: vitals, medications, cycle, sexual activity, and work notes all in one place. Accurate cycle forecasting with reminders. Full functionality in the base version without restrictions.

No menopause mode: during irregular perimenopausal cycles, the app suggests pregnancy mode, which is confusing. The interface has not been updated and some features feel outdated. The screen occasionally freezes and stops responding to taps.

Those who want a complete tracker without a mandatory subscription and are fine with a simple interface.

Daily food and activity recommendations tied to the current cycle phase: users say they understood for the first time why some days are low-energy and others feel effortless. Helps women with bipolar disorder distinguish hormonal states from symptoms.

Data disappears when logging out, and signing back in is sometimes impossible. You cannot log a period longer than 10 days since the app simply does not allow it. For women in perimenopause or postpartum, the phase rhythm does not fit and predictions create anxiety instead of helping.

A woman aged 25 to 38 who wants to engage consciously with her cycle and is willing to pay for a detailed wellness journal.

Complete FAM observation in one place, the Wink thermometer, the ability to see personal patterns spanning several years, and educational content based on Toni Weschler's book.

The forecast does not recalibrate for short cycles even after ten years of data. Data disappears during updates. Support is unavailable or completely unresponsive.

Those practicing the fertility awareness method who have already read Taking Charge of Your Fertility and want a digital chart instead of a paper one.

Accumulated accuracy for long and irregular cycles: the longer you track, the more precise the prediction. A mature interface without excess animation or pastel tones. Data going back to 2013 stays stable for long-term users.

History in the base version is cut to the last six months, which breaks the main value proposition for those who have tracked for years. Cycles longer than 99 days during perimenopause are not supported. Shortened symptom labels after an update have become hard to read.

Those with irregular cycles who are willing to use the app for at least 3 to 4 months so the algorithm can build accuracy.

Accuracy for irregular cycles improves over years: users with long history say the app has become more accurate than any other tracker. The neutral icon and name do not stand out on the home screen.

After recent updates, a full-screen banner appears after every action, and it is sometimes impossible to close before a timer runs out. No built-in symptom analysis or phase-based recommendations. Symptom logging features are minimal compared to competitors.

A woman with an irregular cycle who needs an accurate, simple tracker with no educational content: just a forecast and history.

Women say they finally feel seen: symptoms their doctors dismissed have explanation and context here. Being able to show a symptom journal to a doctor is consistently named the top practical benefit.

No option to add custom symptoms or triggers beyond the built-in list. The period end date often does not save. Women without a uterus cannot complete setup correctly. Date formats are not adapted to the American standard.

Women aged 40 to 60 in perimenopause or menopause who need a structured symptom journal for conversations with their doctor.

A dragon that grows from daily meditations and symptom logging: a concrete mechanic that prevents skipping. Personalized phase tips and mood explanations reduce anxiety. The dragon widget on the home screen becomes a reminder without pressure.

The app sometimes freezes and fails to load, especially when opening the morning meditation. Contraceptive cycles are not supported: there is no way to account for the effect of hormonal methods on predictions. Past symptom history is not viewable.

A woman who wants to build a daily cycle awareness ritual through gentle gamification, with a focus on wellbeing rather than contraception and without medical anxiety.

Clean interface without constant ovulation and conception reminders: rare in this category. Neutral visual style does not announce the app's purpose. Simple enough for a first-time user.

Notes disappear when you try to edit them: typed text vanishes without saving. The notes feature has not been updated in a long time, suggesting no active development. Some content in the announcements section is occasionally inappropriate for a teen audience.

Those who need a clean countdown with no fertility agenda: people not planning pregnancy, those dealing with infertility, or anyone who prefers minimalism.

Fertile window prediction updates in real time as new data comes in: doctors recommend Ovia as the most accurate conception tool. Detailed logging across symptoms, mood, nutrition, and over 40 parameters. Ovulation tracking is available in the base feature set.

With an irregular cycle, especially postpartum or after a miscarriage, predictions barely work and the app does not adapt to the changed rhythm. Pregnancy loss is not handled correctly. The merger with the pregnancy app caused data loss for some users.

Women planning pregnancy with a reasonably regular cycle who are willing to enter data daily.

Simple data entry and Face ID authentication mean no one else can see the data. Multi-year data stays stable for long-term users. A countdown widget to the next period start.

The ovulatory phase cannot be edited as flexibly as the menstrual phase. The Stories section includes sexualized content despite a 12-plus age rating. Accuracy for irregular cycles is lower and the algorithm does not adapt to individual rhythms.

A teen or young woman with a reasonably regular cycle looking for a free, simple tracker without much data sharing.

Transparent privacy policy explained during onboarding. Cycle phase notifications with concrete descriptions of the current state. The ability to share your cycle with a partner without a separate account.

Irregular cycle prediction accuracy is criticized even by users who entered three years of history, with deviations of up to two weeks. The astrological wording of daily insights comes across as condescending to part of the audience. The app opens unreliably during phone calls.

Those who switched from Flo due to privacy concerns and want a tracker with a warm, non-judgmental atmosphere, with a regular cycle.

With a stable cycle and consistent measurements, the accuracy is impressive: long-term users know the next cycle date in advance. The feeling of control without hormones is a powerful motivator for the audience that was sidelined by pill side effects.

With an irregular cycle, ovulation is predicted with an error of up to a week, confirmed by users with clinical monitoring. The postpartum period makes the app completely useless. The algorithm does not explain why a day is red or green, which generates anxiety.

A woman with a regular cycle who is willing to measure basal temperature at the same time every day and treats the method as contraception requiring strict discipline.

An AI chat that answers cycle questions: teens say it explains unusual symptoms without panic, replacing anxious internet searches. A wellness journal with phase prompts helps connect cycle and mood.

After hormonal changes or implant placement, the algorithm does not adapt and prediction accuracy drops without recovering. No postpartum tracking mode. Feed content sometimes does not match the audience's age.

A teenager who wants guidance alongside a tracker: for questions they would not feel comfortable asking a parent or doctor.

You can disable everything related to pregnancy and ovulation, enter any custom dates, and store years of history. Works well for teens.

The forecast does not adapt to an irregular cycle. The interface has grown more complex with each update. Data sometimes disappears when switching phones.

Teens and adults with a reasonably regular cycle who want a simple journal without reproductive content.

A hormone chart on the main screen and morning notifications describing the current cycle phase. Contraceptive tracking without a forced selection from a list. The app's tone is neutral and free of anxious phrasing.

No way to go back and mark the start of a cycle on a past date. The calendar screen is unintuitive, with not all period days visible. The app freezes on the loading screen after several months of use.

Those who want to understand the connection between the hormonal cycle and mood and wellbeing, not just know the next period date.

Forecast accuracy for regular cycles, with many writing it hits the exact day. Rich symptom and mood journal. Years of history help identify patterns.

Does not adapt to irregular cycles or the first months after stopping contraception. No way to edit a specific past day without breaking the entire forecast. A documented data-sharing scandal with third parties is real and mentioned in reviews.

Women with a predictable cycle who want symptom history and advance notifications.

A clear visual fertility window calendar, simple LH test and symptom entry, and educational materials.

No way to retroactively log missed periods. Does not adapt to irregular cycles. Cannot add a second period within one month.

Those planning pregnancy with a regular cycle around 28 days who want a clear visual calendar.

European jurisdiction and GDPR: data is physically unavailable to US authorities, and this is the only major tracker with that guarantee. Detailed symptom journal covering endometriosis and multiple cycle parameters simultaneously. Helped with three pregnancies even in the base version.

Does not work without an internet connection, which is critical on planes or with poor signal. Period start date prediction accuracy is lower than competitors. Non-standard family configurations are not supported as a distinct tracking scenario.

Those for whom data privacy is the top priority and who are willing to pay for full functionality.

Designed for teens: explains basic cycle concepts without medical anxiety. Tracks flow volume and symptoms in a simple format. Works as a first introduction to cycle tracking for those just starting out.

The open chat room accessible to any app user is a risk for minors. Parental restrictions can be easily bypassed by the child through settings. Predictions for irregular early cycles are inaccurate without explanation.

Girls aged 10 to 15 with a recent first period, provided a parent has set up the app and explained to avoid the chat room.

Broad symptom list for logging patterns before a doctor visit: several users report identifying recurring patterns through the app. Ten years of history is stored and accessible by scrolling. Recommended by obstetricians as a documentation tool.

The forecast typically arrives two to three days late relative to the actual start: some users have accepted this as a constant offset. Third-party trackers in the interface of some language versions have no close button. Privacy practices raise questions, with some indication that data is shared with third parties.

Experienced users with several years of data who are willing to pay for a subscription and value a rich symptom journal.

Minimal data entry: just the start date and cycle length, and the forecast is ready. Clean interface without extra screens or sections. A good first tracker for teens.

With an irregular cycle, predictions do not adapt: the algorithm keeps using the old average and does not update the model. A mistakenly entered day cannot be fixed without losing several adjacent entries. Lifestyle tips sometimes read as blaming the user when the cycle is unexpected.

Users with a predictable cycle who only need a calendar with no analytics or reproductive content.

With regular use, accurately predicts ovulation. Detailed logging of symptoms, mood, and libido. Historically helped users with infertility diagnoses.

Irregular or postpartum cycles are barely supported and the app does not adapt to changes. The community section is emotionally unsafe. Pregnancy loss is handled offensively.

Women planning conception with a regular cycle for whom community matters.

Phase-specific recipe and workout collections, clear phase navigation, and the sense that the body is behaving predictably.

The period start date cannot be corrected manually. The forecast gets stuck with an irregular cycle. The imagery is perceived as inappropriately sexualized by part of the audience.

Women with a regular cycle interested in nutritional and physical synchronization with their phases, who are willing to accept a limited tracker.

Women with PMDD and prolonged hormonal imbalance say the app was the first to help them see a pattern and feel understood. Daily phase descriptions give language to states that previously felt inexplicable.

The forecast does not adapt to an irregular cycle and locks ovulation on day 14. Past dates cannot be corrected retroactively. The cycle terms (bleed, rise, shift, reflect) are unfamiliar and require relearning. Data has been lost after updates.

Women with a regular cycle who want to understand the connection between hormones and mood, and those who have just come off hormonal contraceptives and are learning their natural rhythm.

Color coding for period, ovulation, and fertility days is readable at a glance. Partner data access through a separate account is noted as a useful feature. Prediction accuracy for regular cycles is adequate based on long-term user reviews.

The screen periodically goes completely white with no way to recover without reinstalling. Data sync with the online account breaks when the password is changed. Support does not respond to reports: several users could not recover lost data.

Users with a regular cycle who want a clear color-coded calendar and the ability to share data with a doctor or partner.

Works without a mandatory account and without aggressive upselling. The icon does not look like a period app, which matters to those who keep their phone private. Simple to set up in a few minutes.

Individual days cannot be corrected retroactively: changing one day resets adjacent entries. Predictions do not adapt to irregular cycles and simply shift the date by the average. Past symptom history cannot be viewed retrospectively.

A girl aged 10 to 14 just starting to track her cycle and not ready to pay.

Real hormone numbers instead of guessing from temperature or mucus. Months of data allow users to see patterns and understand a non-standard cycle. Support is described as responsive by some users.

Wands expire by firmware even when physically still usable. The algorithm prompts testing too early for late ovulators, forcing extra wand use. The app itself is rough: charts are inconvenient for analysis and notifications are pushy and anxiety-inducing.

Those who have already gone through fertility workups and want precise hormonal data rather than a calendar prediction.

Historically one of the cleanest interfaces: flowers on ovulation days, minimal input. Symptom and mood journal available in the base feature set. Cycle syncing shows how to eat and move for each phase.

After the update, weekday labels are wrong throughout the entire history starting in February. With an irregular cycle, the history becomes an unreadable artifact, showing cycle lengths of 487 days.

Would suit those who want a minimalist tracker, but the update has made it unreliable.

A physical sensor registers the moment a pill is removed: less anxiety about whether you took it. The intake history log makes missed days visible. Reduces cognitive load for those taking the pill as hormone therapy who need precision.

The sensor sometimes fails to register pill removal. There is no option for a 3-month pack with a single placebo week at the end. Notification sound is quiet and gets missed without vibration. Buttons in the interface on iPhone Pro Max are awkwardly placed and require scrolling.

Those taking hormonal pills who are willing to pay $99 for the case plus a subscription, and who can accept occasional glitches in exchange for reliable reminders.

Daily messages from the future baby build an emotional connection during the waiting period. Parallel tracking with a partner via HiDaddy syncs the couple's experience. Postpartum features for tracking the baby's growth after birth.

Some messages from the baby are written in a judgmental tone: weight and diet advice reads like criticism. Some medical facts are outdated or inaccurate, with the onset of heartbeat stated incorrectly. Sync between the mom's and dad's accounts is unstable.

Expecting mothers with an uncomplicated pregnancy who want an emotional journal rather than a medical resource.

Users with regular cycles praise ovulation window accuracy and simplicity: open it, check, close it. Several families report successful conception on the first or second try.

No way to correct a past day or set a variable cycle length. Ovulation predictions diverge from test strips by 5 or more days at any deviation from the norm. No symptoms or notes fields. Interface has not been updated and deleting an entry deletes all history.

Only for those whose cycle is stable to the day and who have no need for fine-tuning. Not suitable for irregular cycle tracking or anyone who wants test strip data.

In earlier versions: exceptionally simple and fast cycle logging. Long-term users valued it for interface stability and predictability.

The redesign buried core tracking features behind multiple navigation screens. Irregular cycle support is weak, with no adaptation. Data saves unreliably during updates.

Was well-suited for those wanting a minimalist tracker with no extra features, but the current product state does not match that.

Color-coded days with green for neutral and red for fertile makes cycle navigation visual. Supports two ovulation calculation methods for gender selection, valued by users planning for a specific outcome. Helped couples conceive based on specific reviews.

The forecast consistently runs one day late compared to actual results, confirmed independently by multiple users. The color logic for baby sex selection runs opposite to what academic sources describe, according to some users. Basic data entry requires an extra step across multiple screens.

Those who want a simple free tracker with a minimalist interface for a regular cycle and tracking intimate days.

Extensive symptom list for logging: moods, physical sensations, and cycle parameters. Color-coded days make history readable at a glance without extra text. History transfers across devices for most users.

Irregular cycle prediction is weaker than competitors, typically off by a day or two. Some users lose past cycle length data during updates. Two-factor authentication cannot be disabled without losing account access.

Paid version users without irregular cycles who are not bothered by an outdated UX.

Reminders several days before the cycle starts: specific reviews cite this as the main value. Simple symptom and note logging without account registration.

After an update, the app fails to open for a significant portion of users. On update, period history shifts with past dates showing incorrect entries. The default date on opening is set incorrectly.

Those who want a free tracker without premium pressure and can accept instability after updates.

In the old Eve: accurate predictions even for irregular cycles, a supportive tone without a pregnancy focus, and a convenient cycle phase overview.

After the update, reaching the calendar requires dismissing five popups. The app has been reoriented toward pregnancy, while Eve was positioned for those not planning children. Test strip fertility sync is broken.

Historically, women who are not planning children and want to track their cycle without a pregnancy-centric interface. That audience has now effectively been pushed out.

A clear sleep debt and nightly pattern tracker against Apple Health data. The smart alarm wakes you during light sleep: some users feel a noticeable difference in how they wake up.

The app regularly fails to open, fails to record sounds, and does not use the Apple Watch. It is not a menstrual cycle tracker and does not address period or ovulation tracking in any way.

A user who needs a sleep quality tracker, not a cycle or fertility tracker.

Explains the connection between cycle phase and mood, energy, and need for rest: some users say they understood for the first time why their state shifts on certain days. Journal entries and reminders help with scheduling workloads around the cycle.

Selecting the cycle start date requires clicking one day before the actual date due to an interface bug. Support does not respond to reports. Recipes are limited to vegetarian options, which does not work for everyone.

Users with a regular cycle who want to sync workloads and diet with their phases, given patience with a rough product.

Simple entry and color-coded cycle phases. Several users reported pregnancy on predicted ovulation days.

Cycle length does not save when changed and reverts to 28 days each month. A fixed day-14 ovulation does not apply to irregular cycles. No symptom journal in the base version.

Those with a strictly regular 28-day cycle who only need a calendar with no symptom log.

Before the redesign: detailed phase-specific recommendations on diet, activity, and schedule. The concept clearly explained why energy drops during the luteal phase or sugar cravings spike.

Mass data loss on update, documented across many reviews. Cycle predictions have become inaccurate: the app regularly misses period start. Content has become a supplement sales funnel with no personalization.

Not recommended in its current state. Potentially for a woman with a regular cycle interested in hormonal phases, if the developer restores functionality.

Cycle start reminders and data change reminders work reliably. The phone camera pulse reader as an extra tool is noted as surprisingly accurate by several users.

With an irregular cycle, entered data cannot be correctly edited: changing a date does not recalculate the ovulation forecast. The review request appears literally on every data entry, not just at launch. Mandatory registration before any use with no way to try first.

Those with a stable cycle who want a visually appealing interface with a detailed symptom journal.

Before the redesign: the only tracker with support for the ring, implant, and other non-pill contraceptive methods. No gender labels and no forced pregnancy as a goal: a valuable position for this audience.

Years of data lost after the update, documented across dozens of reviews. Predictions are broken: the algorithm averages incorrectly and does not learn from history. Missed pills or a new pack start date cannot be corrected.

Not recommended in its current state. Target audience: women with non-standard contraceptive methods and a privacy priority who now lack a working tool.

The ability to share a cycle with a partner has found devoted fans. Users for whom the app works note complete functionality and an attractive design.

No email login: without an Iranian phone number, signing in is impossible. The interface language does not switch to English for some users. Cycle start notifications consistently fail to arrive. Server issues log users out.

Persian-speaking users with an Iranian phone number who need a Farsi-language tracker with partner sharing.

Simple data entry for those who just want to know the next cycle date without extra screens. NuvaRing reminders are noted as a rare useful feature. Data transfers when switching phones.

A full-screen banner appears after every action in the app: a new content block after each tap. The interface has not been updated and looks like a pre-2015 app. The app periodically fails to open after updates.

No one using the free version. For those willing to pay for premium and who value prediction accuracy over interface convenience.

Historically accurate cycle predictions, a detailed symptom and mood journal, and cross-device sync when it worked.

Mandatory Apple ID login with two-factor authentication has locked hundreds of users out. Ten to fifteen years of data were lost during updates with no recovery path. The new 2026 privacy policy requires accepting expanded data collection.

No one. The app is in active decay. Users with historical data should export immediately and switch to another tracker.

The forecast breaks after every major update. The period start or end date cannot be easily corrected. Ten to thirteen years of data disappear without warning and cannot be recovered through the standard method.

Those willing to risk their history for a familiar interface who already have a data backup.

Educational content about hormones and cycle phases is structured more clearly than in most competitors. Shows the predicted ovulation date on the main screen without extra steps.

The symptom logging list is limited with no option to add custom entries. Fertility improvement content is repetitive and does not get updated. AI chat responses are auto-generated and do not adapt to the user's specific situation.

Not recommended to anyone until the subscription and terms transparency issues are resolved.

Access to test results and appointment records. Notifications about new messages from the clinic.

Cannot reply to a doctor's message. Notifications do not clear. The interface is unreadable on modern screens. No sync with the main website.

Only patients of clinics that have mandated this platform with no alternative.

The idea of a unified medical portal for communicating with the care team is good. Several users noted that when the app did work, it was convenient to see test results in one place.

Login breaks on every open, there are no notifications at all, support response times are measured in weeks. The app delays urgent medical instructions for patients in critical treatment phases.

Prelude Network patients are required to use it by the clinic. As a voluntary choice, not recommended to anyone.
