Apple Health (HealthKit) is Apple’s central hub for storing your health and activity data from apps and devices. When you connect AlterMe to HealthKit, we securely import select data points—like heart rate, workouts, and weight—to give you a more complete picture of your daily activity and recovery. Popular apps such as Strava, Peloton, and Nike Run Club also sync to Apple Health, which means those workouts can flow into AlterMe as well.
This helps us personalize your readiness score and daily recommendations using all the information your body is generating. To learn more about managing your Health app data and permissions, you can reference Apple’s support article here.
