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.




Low energy, rough sleep, and bad days often follow your cycle phase. Ovuly connects the dots.
Capture flow, symptoms, and mood without turning it into a task. Real patterns need real consistency.
No sign-in, no cloud, no analytics. Your reproductive health data never leaves your device.
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.
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.




A clear calendar when you need the whole story.
Check upcoming predictions, review historical cycles, and keep everything in one place without losing the nuance of day-to-day context.
