At the Apple Watch event this week, the company revealed information on their next big medical and health pus: ResearchKit. After talking up HBO NOW on Apple TV and a bit about CarPlay, Apple's event turned toward Medical Research. Apple's Senior Vice President of Operations Jeff Williams stepped onstage to introduce ResearchKit. This system, said Williams, "turns iPhone and HealthKit into powerful tools for medical research." This system would have "hundreds of millions of iPhone owners out there" contributing health data - since they'd "gladly contribute," so says Williams.
