Vela

Vela is a private, on-device period and cycle tracker built for people who want accurate predictions without handing their health data to a server.

TRACK WHAT MATTERS

• Log periods, flow, symptoms, mood, and journal notes in seconds

• Track basal body temperature (BBT) alongside your other signs

• See your fertile window and estimated ovulation day

• Get cycle predictions that improve as you log more — with a visible confidence range (±4 days on your first cycle, down to ±1 day after 6+ cycles)

PRIVATE BY DESIGN

Your cycle, symptom, mood, and journal data stays on your device. Vela has no server for your health data and never sends it anywhere. The only network activity is processing purchases and subscriptions through Google Play and RevenueCat — and those services only ever see purchase status, never anything about your cycle or health.

Optional PIN and biometric (fingerprint/Face ID) app lock adds an extra layer of privacy if you share your device.

GO PREMIUM (OPTIONAL)

Everything you need to track your cycle is free. Vela Premium adds:

• Advanced insights into your personal cycle patterns

• PDF & CSV export of your data

• Smart reminders, including pill reminders

• Premium themes

Vela is intended for wellness and personal tracking purposes only. It is not a medical device and does not provide medical advice, diagnosis, or treatment.

No account. No ads. No data selling. Just your cycle, on your terms.
