Perry: Period Tracker

Perry is a simple, private way to log your periods and see your next cycle coming. • Log a period with one tap when it starts, and add the end date when it ends. • Cycle dial: see which day of your cycle you're on and how many days are left until your next period. • Calendar: logged periods, predicted periods, fertile window and ovulation day in one view. • History: every cycle as a strip on the same scale, with your average cycle, average period length and cycle range. • Predictions use the average of your last 6 cycles; you can also set cycle and period length manually. • Light and dark theme, English and Turkish. Privacy first No account, no ads, no tracking. Your records are stored only on your device and are never sent to a server. Whenever you like, save a single-file backup to Google Drive or your device and restore it later. Important Perry is not a medical device. Predictions are based on your past records and are not exact; do not use them as birth control.
