Great App

Ive been doing interval running for years and its always been a struggle to hear my interval watch over my music. This totally solves that problem. I also like the pre-programmed runs on there as it has thrown a little variety into a stale routine. Definitely worth the money considering it just replaced a $35 watch without losing any features. Also easier to program than my watch!
