Enter Moov, a soon-to-be-released (this summer) device plus app that not only tracks your fitness, but offers advice for improving your game.
If you run, Moov analyzes your foot strike. If you swim, it analyzes your strokes. If you bike, it analyzes your cadence. It also offers advice for your boxing and weight workouts with yoga and golf coming soon after launch.
Moov will be available this summer and has a pre-order price of $59.95.
My request: Hockey, of course!
