ResearchKit is off to a good start:

Stanford University researchers were stunned when they awoke Tuesday to find that 11,000 people had signed up for a cardiovascular study using Apple Inc.’s ResearchKit, less than 24 hours after the iPhone tool was introduced.

“To get 10,000 people enrolled in a medical study normally, it would take a year and 50 medical centers around the country,” said Alan Yeung, medical director of Stanford Cardiovascular Health. “That’s the power of the phone.”

Bloomberg’s article has also initial numbers for the various apps announced by Apple last week. As I argued in my thoughts on the March 9th event, ResearchKit has the potential to bring change to millions of people.
