RedCalendar — Cycle Tracker

This is a completely new app: the calendar, the sync and every screen have been rebuilt from scratch. All your data is here — cycles, marks and comments are carried over from the previous version the first time you sign in. A new calendar • Pick any day right in the calendar — the day card opens on it, and a swipe moves it along • Period, fertile window and ovulation predictions right in the grid: confirmed days are filled, predictions are outlined Your day • Mark a period as started or ended in one tap • Flow: light, moderate or heavy • Ovulation: automatic, confirmed, a day you pick yourself, or none • Comments and your own tags for symptoms, mood and anything worth remembering • Mark a new period as started while the previous one was never ended, and it is confirmed for you Statistics • Average cycle length and average period length over 6 months, a year or all time • Cycle history with a chart Sync and devices • Everything works offline — your changes reach the server on their own once there is a connection • One account on several devices, with a list of the sessions that are active • Sign in with email Predictions refine themselves Cycle length, period length and the luteal phase are measured from the cycles you record. You can still set the values yourself in your profile. Notifications Reminders for the start and end of your period and for ovulation. One switch turns them off. Appearance Three accent colors — coral, rose and berry — and a dark theme. If you used to sign in with a phone number, add an email in your profile to be sure you keep access to your account.
