Was excited to use this, but was disappointed. This app didn't work well with my music app (radio or downloaded music); it would shut the music off after a few minutes. Also, the app would countdown when to start work (part of the time), but not when work started. Thus, unless I was watching the counter, I didn't know when to switch. I don't really care to run while looking at the screen. Also, I couldn't set how many loops or rounds I wanted and thus had to keep track.
