iPhone

A private period tracker with a calendar and predictions that say how sure they are. No account, no server. Logging and predictions are free forever. Most period apps show a confident date even when they're guessing. Cycle tells you how sure it is: "usually lands in this window, about 9 in 10 by your own history", an honest estimate that gets sharper as you log. PRIVATE BY DESIGN No account. No server. No ads, analytics or tracking. Your logs live in one file on your iPhone. They only leave if you export them or turn on Apple Health. Delete everything in Settings and it's truly gone. A CALENDAR THAT MAKES SENSE • Logged periods, predicted periods and a fertile estimate on one month view • Tap any day to log or edit it • Light and dark mode PREDICTIONS THAT LEARN YOU • Interactive cycle ring: drag to any day and it explains itself • Learned from your own recent cycles, newer ones weighted more • Says "estimate" until it has seen 3 cycles • Irregular cycles get a wide, honest window instead of a fake date • Pause predictions on birth control, in pregnancy or postpartum LOGGING IN SECONDS • One tap from anywhere, plus "Period started?" when it's due • Flow, 0-10 pain with plain anchors, and symptoms • No streaks, no guilt ALSO FREE • Face ID lock and discreet reminders • Apple Health sync (only what you log, never predictions) • Export as JSON or CSV • Health alerts that say when something is worth asking a doctor about CYCLE PRO (OPTIONAL) • All patterns from your logs, like "headaches cluster in the 3 days before your period" • Pain by cycle day • A one-page doctor report (PDF) • Answers in Ask that use your own logs • Custom symptoms Plans: Monthly $2.99, Yearly $19.99 with a 7-day free trial, or Lifetime $39.99 one-time. Prices may vary by country. Subscriptions renew automatically at the price shown unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID. Manage or cancel any time in Settings > your name > Subscriptions. Logging, the calendar and predictions stay free forever.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

A big redesign, still 100% private. • New Calendar: see logged periods, predicted periods and your fertile estimate at a glance. Tap any day to log or edit it. • Light and dark mode, following your iPhone. • Log from anywhere in one tap, and a quick "Period started?" button when it's due. • Clearer predictions: Cycle tells you how sure it is, in plain words. • New Settings screen with reminders, Face ID lock, Apple Health, export and delete. • Cycle Pro (optional): all your patterns, pain by cycle day and a doctor report. Logging, the calendar and predictions stay free forever. • Have a code? Redeem it in Settings. No account. No server. Your logs stay on your iPhone unless you export them or turn on Apple Health. Cycle is not medical advice and not birth control.
