ResearchKit

researchkit-iconResearchKit is an open source framework introduced by Apple that allows researchers and developers to create powerful apps for medical research. 

Easily create visual consent flows, real-time dynamic active tasks, and surveys using a variety of customizable modules that you can build upon and share with the community.

 And since ResearchKit works seamlessly with HealthKit, researchers can access even more relevant data for their studies — like daily step counts, calorie use, and heart rate.
