Great for picking up speed
I really love this app and use it most frequently on the treadmill.
As an upgrade, Id love it if you could program your own custom intervals. For instance, to set it for tempo runs or hill repeats. Im using a training program right now that I think would be complemented by this app if I could adjust the intervals to fit the workouts.
