A few ResearchKit apps were launch partners when Apple first announced the framework, but starting today it is being released to all medical researchers who want to make use of it.

From Apple’s press release:

The first research apps developed using ResearchKit study asthma, breast cancer, cardiovascular disease, diabetes and Parkinson’s disease, and have enrolled over 60,000 iPhone users in just the first few weeks of being available on the App Store. Starting today, medical researchers all over the world will be able to use ResearchKit to develop their own apps and developers can also contribute new research modules to the open source framework.

As noted above, Apple is releasing ResearchKit as an open source framework, and they’ve actually uploaded the entire framework to GitHub, so anyone can see, use, and contribute to the project.
