Useful interval timer

This interval timer is pretty good compared to some competitor apps. It has "work" and "recovery" intervals which you can set to any time for both (thats a feature missing from some competitor apps). One improvement Id like to see would be the option to have a countdown timer on one or the other "work" or "recovery" timers. Right now if countdown is turned on it will play on both the "work" and "recovery" timers.
