Apple built its ResearchKit platform in part to get many more people signing up for medical studies, and it appears to be delivering on that promise in spades. The early partners tell Bloomberg that they got thousands of volunteers within a day of launch, including 11,000 for a Stanford University cardiovascular trial -- for context, Stanford says that it would normally take a national year-long effort to get that kind of scale. The flood of data will theoretically improve the quality of the findings, especially since the automatic, phone-based tracking should prevent people from fibbing about their activity levels.
