Tuwa synthesizes HRV, resting heart rate, sleep duration, and your morning wellness check-in into a daily readiness signal. Each factor is weighted based on its reliability and your personal baseline, with plain-language explanations that support the app's go, modify, or hold verdict.

Yes. While Tuwa reads HRV, heart rate, and sleep data from HealthKit (which Apple Watch, Whoop, Oura, and Garmin provide), you can still log workouts, track load, and use wellness check-ins without any wearable. Recovery scoring accuracy improves with HealthKit data but is not required.

All data is stored locally on your device using SwiftData. The app works fully offline. When you use cloud features (multi-device access), only composite scores sync to our servers -- raw HealthKit data never leaves your device.

Subscriptions are managed through Apple. Go to Settings > Apple ID > Subscriptions on your device to view, change, or cancel your Tuwa subscription. Cancellation takes effect at the end of your current billing period.

ACWR stands for Acute:Chronic Workload Ratio. It compares your recent training load against a longer-term average. Tuwa treats it as workload context, not injury prediction: recent workload and spike flags are shown before training so you can review volume, intensity, or timing with the latest saved data in mind.

Tuwa starts by setting up your training profile and building from your wellness check-ins, logged workouts, and any HealthKit data you permit. With little recovery history, the app stays conservative instead of using population baselines. As real data accumulates, scores become increasingly personal.
