About this app
A period and cycle diary that asks nothing of you first - no account, no sign-up, no ads.
- One tap to record
Log when your period starts and ends, how heavy it is, and how you're feeling, from a simple calendar.
- A next-period estimate, shown as a range
Once you've recorded 3 cycles, the app shows an estimated range for your next period, calculated from your own past cycles - never a single date presented as certain.
- Calendar that tells recorded days from estimated days apart
Recorded days and the estimated range are always shown differently, so you never mistake one for the other.
- A private space to reflect
See your cycle length over time and how much it varies. Free shows your most recent 6 cycles; a one-time purchase unlocks your full history.
Free forever: recording, calendar, the next-period estimate, app lock, export/import, and reminders. A one-time purchase unlocks unlimited custom tags and your full cycle history.
- Completely private
No account, no ads, no tracking, no internet connection required. Nothing you record is ever sent anywhere - it all stays on this device. Add an app lock (Face ID/passcode) for extra privacy.
Available in 9 languages: English, Japanese, German, French, Spanish, Korean, Traditional Chinese, Vietnamese and Portuguese.
This app is not for contraception, and does not tell you if or when you can get pregnant. If you have symptoms that concern you, please talk to a doctor.
