UPDATE July 20, 2022
Users can now store over 150 different types of health data from Apple Watch, iPhone, and connected third-party apps and devices in one central view in the Health app, in addition to available health records data from connected institutions in the US, UK, and Canada. There are now tens of thousands of apps on the App Store that use the HealthKit API, which allows developers to incorporate data users choose to share from the Health app to offer innovative health and fitness experiences, with rigorous privacy and data security protocols. The report spotlights examples of globally popular HealthKit-enabled apps like Nike Run Club, Calm, and WeightWatchers, plus an increasing number of HealthKit-enabled apps — including Qardio heart health and Withings Health Mate — that use connected accessories to allow users to track and monitor even more aspects of their health.

Grounded in Science and Designed Around Privacy

  • Rigorous scientific validation processes: Apple’s in-house clinicians are deeply involved in the product development process, and work hand-in-hand with engineers and product designers. This, combined with collaboration with experts from leading research institutions, ensures that products and features are grounded in science and user-friendly.
  • Privacy at the center: Privacy is a core value at Apple, and data privacy is critical for sensitive health data. Apple’s health and fitness features put users’ privacy at the center, and provide users with protections, including transparency and control. When iPhone is locked with a passcode, Touch ID, or Face ID, all health and fitness data in the Health app — other than Medical ID — is encrypted, and any health data synced to iCloud is encrypted both in transit and on Apple servers. And if a user has a recent version of watchOS and iOS with the default two-factor authentication and a passcode, their health and activity data will be stored in a way that Apple can’t read it. Health app data is never shared with any third party without the user’s explicit permission, and if users decide to share their health data, the Health app provides users with granular control over the types of data they share and who they share it with. They can review and manage permissions at any time.
