Apple Introduces HealthKit
As part of iOS 8 Apple also introduced HealthKit, a hub and service that can be used to monitor health and interact with healthcare providers. HealthKit works with third-party apps, such as those from the Mayo Clinic, to collect and sync data from iOS devices to the owners' doctor's office. Apple envisions HealthKit as a central repository for all the health apps running on a device. Developers will be able to hook into the service to enrich peoples' ability to track and manage their health.
