ResearchKit has the capacity to truly change things. Today, Apple is letting Developers and researchers realize its promise, and has opened ResearchKit up to anyone who wants to contribute. Developers are now free to develop apps that utilize the framework, and researchers can begin new studies to aide in ramping up their studies. Announced at Apple’s March event, ResearchKit uses an iPhone as a diagnostic tool when users opt-in to providing data. On launch, Apple and a few select partners had medical studies relating to Breast Cancer, Parkinson’s Disease, Asthma, and Cardiovascular Disease.
