Apple Watch & Widgets
Readiness, workouts, and macros on your wrist and Home Screen — synced with iPhone in real time.
Apple Watch app
Install Hammr on iPhone and the Watch app auto-installs. Three tabs: Readiness shows four rings for Readiness, Recovery, Mental Stress, and Sleep; Workout shows active session UI or shortcuts; Nutrition shows macro progress, water, and quick text meal logging.
During workouts the Watch mirrors phone sessions with exercises, sets, rest timer, and live heart rate via HealthKit. Adaptive decision numbers push to Watch including macro deltas and volume percentage.
Widgets and complications
A four-ring Home Screen widget shows Readiness, Recovery, Mental Stress, and Sleep without opening the app. Tap a ring to open the relevant detail screen. Watch face complications surface scores at a glance.
Widgets update via background fetch and silent push, especially after Oura sync. Onboarding and Settings include setup guides.
Sync
WatchConnectivity handles real-time session sync between phone and watch. Water and meal logs on Watch update iPhone immediately. Watch recovery data is what drives the closed loop on iPhone.
Hammr is available on iOS with Apple Watch support.
