### 5/5 — Great loop timer

*2015-02-22*

I kept trying timer apps until I found this one. I wanted one that would count down while I stretched and buzz when the timer ran out and then looped. This one does all that and more and ever lets me listen to music while it is running in the background. Thanks for the great app!
