With the launch of ResearchKit, Apple has turned the iPhone into a medical research tool. ResearchKit makes it possible to generate large, wide-ranging datasets about the day-to-day of disease. Additionally, it allows researchers to recruit participants for large-scale studies. Bloomberg Business reported that 11,000 people had signed up for a cardiovascular study at Stanford University 24 hours after ResearchKit was introduced. Researchers at UCLA have already developed an app with ResearchKit for breast cancer, called Share the Journey: Mind, Body and Wellness after Breast Cancer – this app builds on the work of applied mathematician and TED Fellow Max Little. If you’re interested in finding out more about how Max Little’s work influenced the development of ResearchKit, you can watch his TED talk from 2012: A test for Parkinson’s with a phone call.
