Top 10 Best period tracking apps 2026
Cycle apps have quietly become one of the most used health tools on a phone, and the wrong pick costs more than a wasted subscription. This rating collects period tracking apps for people who want to see the pattern behind an irregular cycle, plan a pregnancy or avoid one, walk into a gynaecology appointment with real dates instead of vague recollection, or simply understand why the same week every month feels heavier.
Selection started with method rather than design. What predicts the next period: plain calendar averages, machine learning on aggregated data, or basal body temperature and symptothermal rules. Whether the app is a certified medical device or a diary with decoration. Where the data lives, who has touched it in the past, and what a privacy policy actually permits. Then the practical layer: how much of the tracker works for free, what the subscription really costs, whether history can be exported for a doctor, how many symptoms can be logged, and how loud the ads are.
Places here are set by community votes, not by the editors and never by payment. The shortlist is editorial; the order belongs to readers. Open a card before installing anything: the pros, the cons and the reviews say more about daily use than any feature list, and no period tracking app replaces a clinician when bleeding, pain or cycle length change without explanation.
Launched in 2015 and run from London, Flo is the most downloaded cycle app in the world, with installs counted in the hundreds of millions and tens of millions of women opening it every month. Predictions run on machine learning trained on aggregated cycle data, and the in-app articles are signed off by a medical board. Anonymous Mode, added in 2022, lets an account exist without a name or email address. Premium adds deeper reports, symptom analysis, pregnancy and postpartum modes.
Suits anyone who wants a polished free tracker, reminders that arrive on time and a community to ask awkward questions in. Worth knowing before signing up: in 2021 the FTC settled with Flo over health data shared with analytics providers, so the privacy record is trust rebuilt rather than trust never broken.
- Free version covers everyday tracking
- Anonymous Mode without name or email
- Content reviewed by doctors and researchers
- Detailed symptom and cycle reports
- Pregnancy and postpartum modes included
- Past FTC case over data shared with analytics
- Constant nudges to buy Premium
- Predictions drift on very irregular cycles

Berlin studio BioWink released Clue in 2013 and never repainted it pink: neutral colours, adult language, numbers first. Around thirty symptom categories, cycle statistics, PMS and ovulation windows, plus an encyclopaedia at helloclue.com written with clinicians. In 2021 the company received FDA clearance for Clue Birth Control, a digital contraceptive based on cycle history. The company operates under EU data protection law and states that it does not sell personal data.
A comfortable choice for teenagers and for anyone tired of flower icons and horoscopes. Clue Plus, the paid tier, adds analysis and forecasts, while core tracking stays free. Users who chart basal temperature and LH tests as a serious fertility method will find the toolkit thinner than in dedicated charting services.
- Sober design without pink infantilism
- FDA cleared birth control mode in the US
- EU privacy rules by default
- Free tier keeps core tracking
- Strong medical explainers on the website
- Needs several logged cycles to predict well
- Analysis and forecasts sit behind Clue Plus
- Thin tools for temperature charting
- Dry interface for first time users
Swedish app created by physicist Elina Berglund, CE marked in 2017 and cleared by the FDA in 2018 as the first application approved for contraception in the United States. The algorithm reads basal body temperature, measured every morning with the supplied thermometer or pulled automatically from an Oura Ring or Apple Watch. Green days mean no protection needed, red days mean protection required. The company states 93 percent effectiveness with typical use and 98 percent with perfect use.
Works for disciplined users with a stable sleep routine who want a hormone free method with visible numbers. Night shifts, alcohol, fever and short nights distort temperature and produce long stretches of red days. Nothing here protects against infections, and the subscription is the only way in.
- FDA cleared for use as contraception
- Hormone free method with clear daily rules
- Syncs with Oura Ring and Apple Watch
- Thermometer included with the annual plan
- Separate postpartum and perimenopause modes
- Subscription only, no usable free tier
- Daily measurement discipline required
- Many red days after illness or bad sleep
- No protection against infections
Ovia Health started in 2012 and has belonged to Labcorp since 2021. Three connected apps cover cycle, pregnancy and early parenting; the cycle app logs periods, ovulation, cervical fluid, temperature, medication and moods, then flags patterns worth showing a clinician. A large share of users arrive through employers and health plans, which unlocks premium content, health coaching and care navigation at no personal cost.
Made for people trying to conceive who like structure: fertile window, cycle reports, clinical articles and reminders for tests. Outside the United States the employer channel rarely applies, so part of the value disappears. An account with an email address is mandatory, and the free feed pushes a lot of reading material.
- Clinical backing from Labcorp
- Free cycle and fertility tracking
- Employer plans unlock coaching and content
- Reports that are easy to show a doctor
- Detailed logging of fertility signs
- Main perks tied to US employer benefits
- Account with email is mandatory
- Feed crowded with articles and prompts
- Predictions plain compared with charting apps
Glow appeared in 2013 from the incubator of PayPal co-founder Max Levchin and grew into a family of apps: Glow for cycle and conception, Eve for younger users, Nurture for pregnancy, Baby for the first years. The tracker takes periods, intimacy, ovulation tests, temperature and medication, and the forums are among the busiest in this category. Support answers by email and on a US phone line during weekday hours.
The draw is community plus longevity: plenty of accounts here hold eight or ten years of history with charts and exports across all of it. The cost is advertising in the free tier and analysis behind a paywall. In 2019 Consumer Reports flagged weaknesses in account security; the company fixed them, though cautious users still factor that in.
- Large and active community forums
- Family of apps from cycle to baby
- Ovulation test and temperature logging
- Phone support on US business hours
- Years of history kept in one account
- Ads and upsells in the free version
- Security issues reported back in 2019
- Screens loaded with feeds and quizzes
- Full analysis requires a subscription
New York app from 2021 that went viral in 2022 on the back of loud privacy promises and an unusual angle: the cycle is displayed next to moon phases with astrological framing. Underneath the decoration sits an ordinary tracker with periods, symptoms, mood, energy and daily prompts, wrapped in streaks that make logging feel like a habit game rather than paperwork.
Reasonable for anyone who enjoys the aesthetic and wants a light picture of the cycle without medical vocabulary. Not built for clinical planning: no temperature interpretation, no contraception claims, thin statistics. Researchers in 2022 found the app passing user phone numbers to a third party service, which the developers then addressed, so the privacy policy is worth reading before the first entry.
- Simple logging with daily prompts
- Distinctive visual style with moon phases
- Reminders that are easy to keep up with
- Core tracking available free
- Support answers by email
- Astrology mixed into health content
- No temperature or serious fertility tools
- Privacy claims questioned in 2022
- Extended insights only on the paid plan
A nonprofit tracker from Women Help Women: free, with no accounts, no advertising and no analytics. Everything logged stays on the phone. There is a passcode, an instant wipe and a timer that deletes entries automatically. Beyond periods and symptoms, Euki carries vetted information on contraception, abortion, miscarriage and aftercare, in English and Spanish.
The obvious pick for people whose first question is who else can read their cycle data, including anyone in a jurisdiction where reproductive health records carry legal risk. The price of that position: no cloud backup, so a lost phone means lost history, and predictions stay basic next to algorithm heavy competitors.
- All data stored locally on the device
- No account and no tracking
- Passcode lock and instant data wipe
- Free, without subscriptions or ads
- Reproductive health guides vetted by experts
- No cloud backup or device transfer
- Basic predictions and statistics
- No wearable integrations
- Updates arrive rarely
An open source cycle tracker from the Berlin collective Bloody Health, published under a free licence and distributed through F-Droid and Google Play. drip implements the symptothermal method: temperature, cervical mucus and cervix observations feed rule based logic that returns a fertility status the user can trace step by step. The database stays on the phone, can be protected with a password and exported as a file nobody else holds.
Made for two kinds of people: those who want to read the code that judges their fertility, and those who study fertility awareness properly. It demands effort in return. The method has to be learned, the interface is spartan, and the project moves at the pace volunteers can manage.
- Fully open source code
- Transparent symptothermal rules
- Encrypted local storage
- Available through F-Droid
- No ads, no accounts, no payments
- Spartan interface with a learning curve
- Development depends on volunteers
- No cloud sync or backup service
- Requires knowledge of the method
The charting veteran of this category: the service has been running since 1998 and the app inherits that history for better and worse. Automatic ovulation detection, coverline, colour coded fertility calendar, ovulation test logs and a searchable gallery of shared charts numbering in the hundreds of thousands for comparing patterns. Newer versions import temperature and sleep from Oura, Fitbit and Pixel Watch, and there are no ads.
Depth of charting is where it wins, which makes it a long standing favourite for conception over many cycles and for conversations with a fertility specialist. Newcomers often find the density overwhelming: the visual language belongs to a spreadsheet, and the most useful analysis sits in the paid VIP tier after a trial that needs no card.
- Ovulation detection refined since 1998
- Detailed temperature charts with coverline
- Huge gallery of real charts to compare
- Imports data from Oura and Fitbit
- Trial of premium features without a card
- Dated interface and dense screens
- Steep learning curve for beginners
- Best analysis behind the VIP tier
- Overkill for casual period tracking
Since iOS 18 and macOS Sequoia, Apple's password store is a standalone Passwords app rather than a buried settings screen, and it costs nothing. Shared groups let a family put streaming, utility and Wi Fi logins into a common pool where everyone with an Apple Account can edit them, while passkeys, verification codes and Wi Fi credentials sync through iCloud Keychain with end to end encryption.
For a household entirely on iPhones and Macs this replaces a paid subscription outright, with autofill built into Safari and third party browsers via extension. It falls apart the moment someone uses Android, since there is no app for it, and Windows support depends on the iCloud for Windows extension. There is no admin oversight, no breach storage for documents and only basic export.
- Free with any Apple device
- Shared groups for family logins
- Passkeys and verification codes built in
- End to end encrypted iCloud sync
- Standalone app since iOS 18
- No Android application
- Windows support is limited
- No family admin controls
- Basic import and export tools
