Vela: Period & Cycle Tracker

Your cycle, your device, your rules. Vela keeps all health data on your phone with zero-knowledge encryption. No account required. No data ever leaves.

Vela is a private period tracker and cycle tracker that keeps your health data on your device. No account required. No cloud uploads. No data sharing. Your menstrual cycle information is yours alone.

PRIVATE PERIOD TRACKING, BY DESIGN

Every period tracker promises privacy. Vela delivers it with zero-knowledge architecture. Your cycle data stays on your phone, protected by iOS Data Protection. If you choose cloud backup, your data is end-to-end encrypted before it leaves your device. Even Vela's servers cannot read your health information. No sign-up required. No email. No phone number. Open the app and start tracking your period immediately.

ACCURATE CYCLE AND OVULATION PREDICTIONS

Vela's prediction engine uses clinically-informed algorithms that combine established menstrual cycle prediction methods with weighted moving averages. Your period predictions, ovulation window, fertile days, and luteal phase calculations become more accurate the longer you track. A cycle tracker that learns your unique patterns.

SIMPLE PERIOD LOGGING

Start with one tap to log your period. Add flow intensity, symptoms, mood, and energy tracking when you are ready. Vela begins as a simple period calendar and grows with you. Every tracking category is opt-in. No overwhelming symptom lists on day one.

THE GARDEN -- BOTANICAL GAMIFICATION

Watch a botanical garden grow as you track your cycle. Plants bloom from seed to full flower with your consistency. Miss a few days? Your garden waits. Plants wilt but never die. No guilt, no streak shaming. A warm, Studio Ghibli-inspired visual reflection of your self-care journey. The Garden is Vela's signature feature -- a period tracker experience unlike anything else.

INCLUSIVE CYCLE TRACKER FOR EVERYONE

Vela is designed for every body that cycles. No gendered assumptions in language or design. Hormone-aware terminology throughout. Support for HRT tracking for trans and non-binary users. Partner mode works for all relationship types, including dual-cycle tracking for partners who both menstruate.

PERSISTENT PILL REMINDER

More than a notification. Vela's pill reminder stays on your lock screen until you tap "Taken" or "Skip" — designed for real accountability with oral contraceptives.
