Great system with room for improvement!
First off, the app works seamlessly with the device and integrates with HealthKit nicely. It does not measure steps directly, but your activity calories will transfer over to MyFittnessPal. The runs analysis provides a nice rich dataset, but the 7+ minute workouts dont always register every crunch. Overall, I would say it is a pretty great setup, but I would like to see better integration with MyFittnessPal and Spotify.
