HealthKit
Integrate HealthKit into your health and fitness apps for iOS and watchOS to create a more seamless user experience. When a customer provides permission for your app to read and write health and activity data to their Health app, your app becomes a valuable data source and can deliver deeply informed health and fitness solutions.
