Apple Health app in iOS 8

I've upgraded to iOS 8 on my iPhone and I'm now experiencing the new Apple Health app. I'm feeding it with health and fitness data from MapMyRun, MyFitnessPal, and Jawbone UP. Someday, I wonder if the consumer side of health IT interoperability will allow Apple, Google Fit on Android, and Microsoft HealthVault to share data seamlessly. For now, I'll continue to have my health data stored in different silos that don't talk to each other.
