# Apple Health

Apple Health is the iPhone hub that stores workouts, steps, sleep and heart data from Apple Watch and compatible apps.

Workouts are stored as activity samples with type, duration and often distance and heart rate. Strength detail usually needs manual entry or a third-party app. Permissions are controlled in the Health app on iPhone.

Also called: Health app, HealthKit.
