Introduction to Apple's Research Kit

On March 9, 2015, during the Apple Watch Event, the company introduced a new software structure for medical applications. The framework called ResearchKit, is a new platform that medical researchers can use to collect medical data using Apple devices. 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. All the apps built with ResearchKit will enable you to track your own data and potentially discover correlations between symptoms and daily actions such as diet or exercise.
