Great idea. Weak implementation.

Love the option to add different music to different intervals. Unfortunately it isnt really working. You think you are adding a song (which, by the way you CANNOT add playlists, just and individual song. So for warm ups and cool downs you get to listen to one song on repeat) and it doesnt really give you feedback that youve added it. It shows up for a second but if you go back out a level then go back in, it isnt showing up.

The in app music also doesnt override the Apple Music app. I had 2 songs going at once and had to stop the set I was doing to stop the one song that was playing over and over. No way to pause the in app music. Though, it seems you can skip songs. If only you could add more than one song.
