JustPeriod. is a cycle tracker built on two simple principles: your cycle is nobody's business but yours, and the people close to you can be there β only on your terms. SHARE YOUR CYCLE, OR FOLLOW YOUR PARTNER'S β’ Connect with a one-time code β no sign-ups, no accounts to create. β’ Both partners can track their cycles side by side β for every kind of couple, including those where you both have a cycle. β’ Your partner sees exactly what you allow: days, symptoms, predictions or the current phase β every item is set separately. β’ Send a sign of support in one tap, and on period days share what you'd like, in your own words. β’ A quiet widget for the Home Screen and Lock Screen: a name, a phase and a countdown, and nothing for anyone nearby to read. β’ Turn sharing off at any moment β the data disappears from your partner's phone straight away. FOR REAL BODIES AND REAL LIFE β’ Dedicated modes for PCOS, endometriosis, fibroids and PMDD. β’ Predictions that account for your contraception (pill, IUD, implants and other methods). β’ Change your condition or your method at any time β the forecast adapts to the new answers immediately. β’ Honest support for an irregular cycle, with no illusion that a body should run like clockwork. β’ No hints about pregnancy and no pressure around fertility β there is simply nothing here for ovulation or conception. STATISTICS WITHOUT EMPTY PROMISES β’ A clear summary, your cycle history and a cycle map β all on one screen. β’ Average cycle and period length come with their real spread, not a single "perfect" number. β’ The intensity scale shows your usual flow and marks the days it departs from it. β’ The cycle map shows which days particular symptoms tend to fall on. PRIVACY AT THE FOUNDATION β’ All your data is kept on your device alone, protected by iOS encryption. β’ Optional sync and shared access are protected by end-to-end encryption: we could not read your data even if we wanted to. β’ No accounts, no ads, no analytics. Your data is never passed to anyone. β’ Face ID / Touch ID / PIN to get in, and an instant privacy screen. β’ Protected export with a password (PDF, CSV, JSON) and encrypted backups. β’ A simple, quick move of your history from Flo, Clue or WomanLog in a couple of minutes. EVERY BASIC FEATURE, AT ITS BEST β’ A calendar and predictions that fit your settings completely. β’ More than 20 built-in symptoms, and room to create your own. β’ Private notes on any day β kept in your history and included in exports. β’ Handy widgets for the Home and Lock Screens, plus an Apple Watch app. β’ Discreet reminders that give away no details in notifications. HONEST, TRANSPARENT PRICING Every basic feature β tracking, calendar, statistics, import, export, backups and reminders β stays free forever. Shared access and themes open with a single lifetime purchase: no subscriptions, no hidden charges. JustPeriod. Know your body. On your terms.
