Doctors around the world are using iPhone to transform the way we think about health. Apps created with ResearchKit are already producing medical insights and discoveries at a pace and scale never seen before. That success has inspired us to widen the scope from medical research to personal care with the introduction of CareKit — a framework for developers to build apps that let you manage your own well-being on a daily basis.
Adding HealthKit into your iOS and watchOS apps creates a more integrated user experience. When a customer provides permission for your app to read and write health and activity data to their Health app, your app can become a valuable health data source and it can use the shared data to bring more powerful health and fitness solutions.
