Apple's health ambitions, at one point, went way further than adding a blood oxygen monitor to the Apple Watch. According to a new report by the Wall Street Journal, however, those ambitions have largely been cast away — for now. 

Apple wanted to launch its own primary care medical service, with its own clinics and doctors employed by the tech giant, the report says. It wasn't just an idea on paper; Apple tested the plan by building a team of experts and taking over clinics that catered to its employees.
