Almost perfect
Awesome app but oddly it assumes (or seems to assume) that interval workouts always have a ratio that gives more time to resting than working out. I solved it by putting my fast music on the slow setting, but it is odd to the ear to hear "fast" when you go into mode. Speaking of rest, it should also give that as option instead of just slow. Some programs require rest between heavy sets. Nice app otherwise!
