Apple, on GitHub:
ResearchKit 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.
This should silence the naysayers who are always citing FaceTime during discussions of Apple and open source software.
As an aside, there was an episode of The Talk Show in which John Gruber mentioned that the engineers who worked on FaceTime hadn’t heard any discussion of open sourcing FaceTime until Steve Jobs announcing it on stage. Does anyone know which episode that would have been? If so, I’d appreciate it if you could let me know.
