Meet Rinne — the cycle tracker that actually respects you.
Rinne is the only period and ovulation tracker that combines adorable, fully personalized mascots with military-grade privacy. No accounts. No servers. No cloud. No ads. Ever.
YOUR PAST PERIODS, INSTANT PREDICTIONS
Most cycle apps make you wait months before they understand your rhythm. Not Rinne. Enter your period history — one month or twelve — and get accurate cycle predictions, ovulation estimates, and fertile window calculations from day one. The more you log, the smarter it gets.
PRIVACY THAT ISN'T JUST A PROMISE
Your most intimate health data never leaves your phone. Period.
Rinne was built with zero servers. There is no account to create, no email to enter, no data to leak. Your cycle information is stored using hardware-level encryption directly on your device. We couldn't access your data even if we wanted to — because we literally don't have it.
No analytics. No tracking SDKs. No Firebase. No third-party access. Rinne is the cycle tracker built for the post-Roe, post-GDPR world.
CUTE, UNIQUE & TRULY YOURS
Choose your companion: name your Cat or Dog mascot and watch them come to life through every phase of your cycle. Your mascot changes expression with each phase — follicular, ovulation, luteal, and menstruation — making your health journey feel personal and joyful.
Switch between two beautifully crafted themes — a warm pink Cat palette or a cool blue Dog palette — and make Rinne feel like it was designed just for you. Because it was.
EVERYTHING YOU NEED, NOTHING YOU DON'T
◆ Smart cycle predictions with confidence indicators
◆ Ovulation & fertile window tracking
◆ Daily health logging: 20 symptoms, 14 moods, cervical mucus, BBT, sleep, energy, exercise, intimacy, medication & personal notes
◆ Beautiful interactive cycle circle & calendar view
◆ Gentle local reminders for periods, fertile days & daily logging
◆ Cycle statistics & phase insights
◆ 10 languages supported
DESIGNED WITH INTENTION
Rinne doesn't want your attention forever. There are no social feeds, no gamification tricks, no infinite scroll. Open the app, log your day, understand your body, and move on with your life. Health tracking should feel calm, not addictive.
PREMIUM — SUPPORT INDEPENDENT DEVELOPMENT
Rinne is made by an independent developer, not a data-hungry corporation. Optional premium unlocks the full experience through the App Store — your subscription is verified on-device and we never see your payment details.
Rinne is not medical advice. Predictions are for informational purposes only and should not be used as contraception or as a substitute for professional medical guidance.
Your body. Your data. Your device. Only yours.
