Dont be fooled by the "almost" in my tittle... I love this app and use it almost daily for tabata training for Crossfit and interval running to train for marathons. My only request is that they add a "warning" feature to give you an indication of when a green interval is about to end, just as you can for a red interval. When I am all-out sprinting for 90 seconds, I often want to know how much longer I have to keep killing myself, and I wish there was a way to set a buzzer so I could know I was near the end, without having to look which slows me down. Other then this, its a fantastic app! (Past reviews complained about the iPhone timer causing the screen to turn off making the app more or less useless. This seems to have been fixed -- I have kept it running for as long as a half hour while doing interval runs and the screen never shut off.)
All in all, SO worth the $00.99! Thanks for a great app.
