About

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 — only on your terms. SHARE YOUR CYCLE, OR FOLLOW YOUR PARTNER'S • Connect with a one-time code — no sign-ups, no accounts to create. • Both partners can track their cycles side by side — for every kind of couple, including those where you both have a cycle. • Your partner sees exactly what you allow: days, symptoms, predictions or the current phase — every item is set separately. • Send a sign of support in one tap, and on period days share what you'd like, in your own words. • A quiet widget for the Home Screen and Lock Screen: a name, a phase and a countdown, and nothing for anyone nearby to read. • Turn sharing off at any moment — the data disappears from your partner's phone straight away. FOR REAL BODIES AND REAL LIFE • Dedicated modes for PCOS, endometriosis, fibroids and PMDD. • Predictions that account for your contraception (pill, IUD, implants and other methods). • Change your condition or your method at any time — the forecast adapts to the new answers immediately. • Honest support for an irregular cycle, with no illusion that a body should run like clockwork. • No hints about pregnancy and no pressure around fertility — there is simply nothing here for ovulation or conception. STATISTICS WITHOUT EMPTY PROMISES • A clear summary, your cycle history and a cycle map — all on one screen. • Average cycle and period length come with their real spread, not a single "perfect" number. • The intensity scale shows your usual flow and marks the days it departs from it. • The cycle map shows which days particular symptoms tend to fall on. PRIVACY AT THE FOUNDATION • All your data is kept on your device alone, protected by iOS encryption. • Optional sync and shared access are protected by end-to-end encryption: we could not read your data even if we wanted to. • No accounts, no ads, no analytics. Your data is never passed to anyone. • Face ID / Touch ID / PIN to get in, and an instant privacy screen. • Protected export with a password (PDF, CSV, JSON) and encrypted backups. • A simple, quick move of your history from Flo, Clue or WomanLog in a couple of minutes. EVERY BASIC FEATURE, AT ITS BEST • A calendar and predictions that fit your settings completely. • More than 20 built-in symptoms, and room to create your own. • Private notes on any day — kept in your history and included in exports. • Handy widgets for the Home and Lock Screens, plus an Apple Watch app. • Discreet reminders that give away no details in notifications. HONEST, TRANSPARENT PRICING Every basic feature — tracking, calendar, statistics, import, export, backups and reminders — 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.

What's New in JustPeriod.

1.1.2

October 7, 2026

Your partner's cycle in a widget, a note on any day, and predictions built from your own cycles. Plus: a rebuilt Partner tab and stronger protection for sync. NEW • Partner widget on your Home Screen and Lock Screen: their phase or cycle day, days until their period, and what they'd love right now. The medium size adds today's symptoms. • A note on any day of the calendar, even without a period or symptoms. Notes travel with your exports, backups and sync. • Cycle length, health and contraception can be changed in Settings → Tracking. Predictions update right away. PARTNER TAB • Everything on one screen: your partner's cycle, who you share yours with, and invitations that haven't been accepted yet. • The calendar folds with a swipe, like on Home. Tap the month to pick a date. • If sharing is paused, you can see on whose side and what to do. PREDICTIONS • After two logged cycles, predictions follow your own history. Recent cycles count for more. • Phases are not named when a cycle is shorter than 20 days or you use hormonal contraception. You see the cycle day instead of a guess. SYNC BETWEEN YOUR DEVICES • The date and status of every record are sealed together with the data. Nothing in between can change them. • Update JustPeriod on all of your devices: sync with a device on an older version pauses until it is updated. Your data is kept safe.
