Of of the things announced today, Apple’s ResearchKit strikes me as the one thing that will have a long-lasting impact on the world. I think Apple might realize it too. Making ResearchKit open source was a main point in the presentation. Until now, taking part in a medical study has usually required traveling to a hospital or facility to complete tasks and fill out questionnaires. With ResearchKit, you can use your iPhone to perform activities and generate data wherever you are, providing a source of information that is more objective than ever possible before.
