Vela: Private Period Tracker

Vela is the private period tracker that tells you what tomorrow likely feels like. It predicts your period, ovulation and fertile window, then learns your own patterns for cramps, mood and energy.
No account. No ads. No data selling. Your cycle data stays on your phone.
Period and ovulation predictions are free forever. Premium starts with a 7-day free trial on the yearly plan.

New: Body Forecast
See likely symptoms, mood and energy for each of the next 7 days, learned on your device from your own logs. "Cramps likely tomorrow, in 4 of your last 5 cycles." No generic averages, and no server reading your data.

New: Cycle Planner
Your next 12 months of periods and fertile windows on one screen. Planning a trip, a wedding or a race? Pick the dates and see the chance they overlap your period.

New: App Icons and Garden Themes
Choose a discreet home screen icon that does not look like a period tracker. Give your Garden new palettes and seasons.

Private by design
No sign-up, no email, no phone number. Your data lives on your phone, protected by on-device encryption, a fingerprint or face app lock and a one-tap panic wipe. Cloud backup and sync are optional and end-to-end encrypted before anything leaves your device, so not even Vela can read your health data.

A cycle tracker that learns you
Predictions blend established cycle methods with a weighted average of your own history, so your period, ovulation and fertile days get more accurate the longer you track. Birth control is taken into account: a pill withdrawal bleed is not treated like a natural cycle.
