Rheya: Private Period Tracker

A period tracker shouldn't take your data. Rheya keeps your cycle private: nothing you log is sent to us. Every feature is free, forever. No ads, no account, no subscription. A PAGE FOR EVERY DAY Each day has a journal page for your flow, mood, energy, pain and symptoms such as cramps, bloating or headaches, plus a note and a photo. As your pages fill up, "Rheya noticed" shares quiet observations, never predictions. PREGNANCY MODE Follow your pregnancy week by week and see how big your baby is. Add doctor visits, baby moments and notes to the calendar, sync appointments to Apple Calendar if you like, and share a keepsake card when your baby arrives. PILL AND MEDICATION REMINDERS Reminders for your pill, medications and supplements: at set times, on chosen days, or around your cycle. Take, Snooze or Skip from the notification, and get a nudge when it's time to refill. Period, fertile window and your own reminders are there too. WIDGETS On iOS 18 or later, Home Screen widgets show your cycle day and phase, or your pregnancy week, and a Control Center button opens today's page. LOCKED AND DISCREET Lock Rheya with Face ID, Touch ID or your passcode. Discreet reminders and widgets hide cycle and pregnancy details, and a neutral app icon is one switch away. YOUR CYCLE, CALMLY The month is right on Home: your logged period, the next predicted period, fertile days, ovulation and the phase you are in. Predictions start from the cycle length you set and adapt to the cycles you log. Running late? Rheya says a few days either way is normal and waits with you, without alarm. Tap a day to move, end or remove a period, or leave an unusual cycle out of your average. NOTHING YOU LOG IS SENT TO US No account, no servers, no analytics, no tracking, and Rheya works offline. If your iPhone or iPad backs up to iCloud, or you turn on Apple Calendar sync, those copies are kept by Apple or your calendar provider, not by us. Erase everything from Rheya's Settings at any time. BRING YOUR HISTORY Coming from another app? Rheya can read your period days from Apple Health, only when you ask, and never writes anything back. CALM BY DESIGN Three themes, a flower that changes with your phase, gentle tips and tonight's moon. GOOD TO KNOW Predicted periods, fertile days and ovulation are estimates based on your cycle length and the periods you log. Rheya is a companion, not a method of contraception, and not medical advice. If something worries you, ask a healthcare professional.
