Apple, on GitHub:
You can get started with ResearchKit by visiting GitHub, now available to all developers for free under the ResearchKit BSD license. Be sure to check out the Overview tab for great links to documentation and sample code to help you start building your research app today. You can even share your favorite modules with the global research community by creating an issue or claiming an existing one from our issue list and send us a pull request.
With ResearchKit having the potential to change medical research forever, the fact that Apple’s doing this in the open is just icing on the cake.
