Has potential

The problem is with the biggest feature of the app...selecting music to go with your training. It says "Select Songs" yet when doing so no indication is given that a song or songs are selected. And when you return to the setup of an "interval" you may recognize one of the song titles you believe you selected, truncated off the screen, and are left wondering, "Did I select the songs I wanted to select?"

Needs some UI work around one of its most important assets.
