HealthKit (Apple)

HealthKit is a software framework developed by Apple that allows health and fitness data from various apps and devices to be securely stored and shared within a unified system. It helps users track their health metrics—such as heart rate, activity, sleep, and nutrition—centrally on their iPhone or Apple Watch. HealthKit enables seamless integration across compatible apps, supporting personalized health insights and data-driven healthcare decisions, all while prioritizing user privacy and data security.
