Private cycle tracking for iPhone

Stop guessing why you feel “off” this month.

Most period apps rely on basic calendar predictions. Ovuly goes deeper, using your Apple Watch data like temperature, HRV, and sleep to help you understand why you feel the way you do, especially on those low-energy days.

Why Ovuly feels different

The days that blindside you have a pattern. You just haven't seen it yet.

Most period apps track your period and stop there. Ovuly reads the Apple Watch signals — HRV, wrist temperature, sleep — that explain why your energy, mood, and recovery shift across the whole month.

Powered by Apple Health
Ovuly blends wrist temperature, HRV, sleep, and resting heart rate into phase-aware predictions that feel grounded in your actual body.
Fast daily logging
Capture bleeding, symptoms, mood, and notes in seconds. The app is designed for consistency, not for busywork.
Insights that connect the dots
See recurring patterns across energy, sleep, recovery, and symptoms so your cycle history starts to explain the present.
Private by design
No accounts, no analytics SDKs, no cloud databases. Your cycle data lives on your iPhone and, if you choose, syncs only to Apple HealthKit — never to our servers.
Phase-aware insights

Plan your month around your body, not against it.

Ovuly shows how your sleep quality, heart rate, and energy shift across each cycle phase — so you can schedule hard workouts, protect your rest days, and stop being caught off guard by the low ones.
