Apple's latest rule in the iOS App Review Guidelines comes on the heels of the public introduction of ResearchKit, an open source framework for building medical research applications. Rule 27.10 now requires apps meant for research on human subjects to gain approval from an ethics board before they will be approved for the App Store.
From Apple:
Apps conducting health-related human subject research must secure approval from an independent ethics review board. Proof of such approval must be provided upon request.
After its limited debut in March, Apple recently made ResearchKit available to medical app developers. As noted above, the framework is open source, letting developers build their own modules on top of it, and contribute them to ResearchKit for future improvements.
