UNDACycle-aware workout tracker

Training that follows the rhythm of your cycle, not against it.

🌊

Five-phase cycle model

Menstrual, follicular, ovulatory, luteal-early, luteal-late — scaled to your own cycle length. Estimates carry explicit confidence and uncertainty.

🏋️

Phase-aware recommender

Weighted, not deterministic. Sports, goals, equipment, recent training, phase confidence all feed a versioned scoring pipeline with a per-session factor breakdown.

🔒

Local-first, SQLCipher-encrypted

Your data lives on your device by default, AES-256 at rest, key in Keychain / EncryptedSharedPreferences. Cloud sync is opt-in and single-user.

🛡️

GDPR-native architecture

Versioned consent per processing type. Explicit provenance on every data point. Data-inventory-per-field. Full delete + export flows.

🔗

Real integrations

Reads from Apple Health, Strava, Intervals.icu (Garmin planned). Writes completed workouts back to Health. Exports to `.fit` and `.ics`. Cross-provider deduplication.

📖

Transparent by default

Every claim in the app maps to a public claims register. Every §21 compliance document is on this site. Every recommendation records its algorithm version.

Not a medical device

UNDA is a fitness and training support product. It is not a medical device. It does not diagnose, prevent, monitor, predict, prognose, treat, or alleviate any disease. It does not replace a doctor, physiotherapist, or other qualified healthcare professional. Full intended-purpose statement.
