Apple first unveiled its Health application and associated HealthKit framework during WWDC earlier this year with a quote from Dr. John H. Noseworthy, CEO of the Mayo Clinic, a development partner for the iOS Health platform. Now a new report from the Star Tribune claims that the Mayo Clinic will have a role in revealing the next-generation health capabilities of an upcoming device at tomorrow’s event.

It’s not yet clear whether this will happen during a look at iOS 8 or during the preview of Apple’s first wearable device and its health-tracking capabilities. Apple is expected to give details about both during the event, along with two new versions of the iPhone.
