Readiness & Recovery
Apple Health & Oura
Connect Apple Watch via Apple Health, Oura Ring via OAuth, or both — Hammr merges sources into one readiness picture.
Apple Health
During onboarding or Settings, connect Apple Health to grant read and write scopes. Hammr reads heart rate, HRV, resting heart rate, sleep, steps, active energy, workouts, SpO2, respiratory rate, wrist temperature, and optional nutrition.
Hammr writes completed workouts, active calories, meals, water, body weight, and mindful sessions back to HealthKit. The Apple Health Dashboard inside Hammr shows activity rings, recent workouts, and heart and sleep summaries.
Oura Ring
Connect Oura via OAuth to sync readiness, sleep, and activity scores from the Oura API. The Oura Dashboard shows 30-day style views with recovery, stress, and sleep cards.
When both Apple Watch and Oura are connected, choose merge priority: Apple first, Oura first, Apple only, or Oura only. Each metric shows which source supplied it.
Nutrition reconciliation
Three modes combine Hammr diary with other apps' HealthKit nutrition writes: Hammr primary, Apple Health primary, or combine split logging for intentional split tracking.
Fitbit integration is built but UI is disabled pending Google verification — do not market Fitbit as a live feature.
Hammr is available on iOS with Apple Watch support.
