Apple Watch running app concept

Experimenting with an Apple Watch running app. The app would have 3 screens. 1) Current Run which is green when the user is running and red when the user stops. 2) Previous Runs and 3) Weather (based on the native Yahoo weather app).

Thanks to Francesco Scalambrino for the watch template. You can find it here:
