Aster tracks hot flashes, mood, sleep and 25+ symptoms, reads your Apple Health metrics on-device, and finds what's driving your worst days - so you can walk into your appointment prepared.
Hot flashes, brain fog, broken sleep - they're hard to recall weeks later when you finally see your doctor.
Aster pairs your symptoms with sleep, heart-rate and activity from Apple Health to surface the links you can't see by hand.
No account, no servers. Everything stays on your device, and Apple Health is read on-device only.
Track vasomotor, sleep, mood, physical, urogenital, skin and digestive symptoms - across the whole transition.
With your permission, Aster reads sleep, HRV, resting heart rate, steps, weight and cycle data - all processed on-device.
Statistical correlation finds what's tied to your worst days - caffeine, poor sleep, stress - without any data leaving your phone.
Add quick notes and lifestyle context to give your patterns meaning over time.
See symptom burden, trends and weekly summaries, so you can tell what's improving and what isn't.
One tap creates a clear report - symptom frequency, health metrics and triggers - for your appointment.
Aster has no account and no servers. Your symptoms and journal are stored only on your device. Apple Health data is read with your permission and analysed entirely on-device - it is never transmitted to us or anyone else.
