Live Workout Engine

On the wrist, Runara renders the exact screens you designed and drives them with a HealthKit workout session, so the app stays foregrounded for the entire effort, no surprise suspends mid-run.

Speed, heart rate, distance, elevation, and cadence update live. Outdoor activities record GPS; swimming engages water lock automatically. State changes land with a precise haptic, and screen transitions take a deliberate 120 ms so numbers stay readable when you are breathing hard.

Every sample flows straight into Apple Health as you go, which means the workout is already saved correctly the moment you tap stop.
