Today Apple’s Jeff Williams announced CareKit, an open source “framework to build apps that empower people to take an active role in their care.” Apple says it’s launching the framework and app in April as a patient-side counterpart to ResearchKit.

Speaking of ResearchKit, Williams said on stage that “virtually overnight, the research studies that we launched became some of the largest in history.” The company hopes CareKit will find similar success with users.

CareKit partners include the University of Rochester, UCSF, Johns Hopkins, PDC NY, Stanford Medicine, and Emory Healthcare.

Here’s a closer look at CareKit.
