WOD Timer Pro by WOD Republic

hey I figured it out... theres slider that are hard to see. that is how you set-up the Timer.....

I use it to train my young athletes. It gives them a visual and audio cue. Its also something new and exciting to them. My only complaint is that the interval timer (the feature you pay for) doesn't always work correctly. Sometimes it will go to the next set, other times it randomly stops.

Couldn't be more disappointed with spending 2.99 on this app. UI is horrible, can't figure out how to change interval / rest times. Very poorly done.
