A beautifully simple period and cycle tracker that lives entirely on your iPhone. No account. No cloud. No analytics. No ads. Ever.
Coming SooniPhone · iOS 17+ · English, German, Croatian
A full Bayesian prediction engine that learns your cycle, updates with every period you log, and honestly tells you when it's uncertain.
Color-coded periods, fertile windows, and ovulation — with a 6-cycle prediction horizon and daily hormone curve illustrations.
Track flow, mood, symptoms, sleep, energy, and intimacy — all in seconds. Your data stays on your device, always.
Optionally read wrist temperature, HRV, and ovulation tests from HealthKit to refine predictions. Read-only — Ovaly never writes.
Home Screen and Lock Screen widgets. See your cycle day, phase, and upcoming events at a glance — without opening the app.
Handles hormonal and copper IUD, pill, implant, patch, ring — with proper post-pill recalibration and a 5-cycle grace period.
Ovaly was built around one promise: your most personal data stays yours. Everything is stored on your device using Apple's SwiftData. Nothing is uploaded, nothing is sold, nothing is shared.
18 guided onboarding screens learn about your cycle, health conditions, and contraception. No account needed.
Log your period and daily symptoms. The Bayesian engine refines its predictions with every cycle you track.
Get phase insights, hormone visualizations, and gentle reminders — all processed on-device, all private.
Ovaly is coming to the App Store soon. Free. Private. Beautiful.
