The Health app puts that data in one place, accessible with a tap, giving you a clear and current overview of your health. You can also create an emergency card with important health information for example, your blood type or allergies thats available right from your Lock screen.

With HealthKit, developers can make their apps even more useful by allowing them to access your health data, too. And you choose what you want shared. For example, you can allow the data from your blood pressure app to be automatically shared with your doctor. Or allow your nutrition app to tell your fitness apps how many calories you consume each day. When your health and fitness apps work together, they become more powerful. And you might, too.

The Health app lets you keep all your health and fitness information in one place on your device and under your control. The information you generate about yourself is yours to use and share. You decide what information is placed in Health and which apps can access your data through the Health app. When your phone is locked with a passcode or Touch ID, all of your health and fitness data in the Health app is encrypted. You can back up data stored in the Health app to iCloud, where it is encrypted while in transit and at rest. Apps that access HealthKit are required to have a privacy policy, so be sure to review these policies before providing apps with access to your health and fitness data.

ResearchKit is a software framework, created specifically for medical research. And its open source so everyone can collaborate to potentially change medicine forever.
