Perfect... Not only can describe each individual interval With colors but also with names. The shadow coming down from the top showing you the remaining Time Is a great plus In addition to the remaining time innumerals. I have used other timers which are Good, But gymboss is great. I should have known As I have used the regular gymboss on the road for many many years!

I'm thrilled with this app- I found it pretty intuitive to use. It's better than I thought, in that I can save so many different combinations of intervals, name them and arrange them according to my daily training plan. The REALLY great cherry on top of the sundae is I can hear both the interval and my music app at the same time- even if I'm listening to loud, driving music. I liked the free version so much I upgraded to the add free to support the company.

Beautiful app but there are a few drawbacks, some of which are really significant: 1) If music is playing, plenty of times when the countdown/beeper starts alerting, the music would go down and never back to normal unless I close the app and reopen it. 2) Can't copy/replicate days or individual exercises. 3) Can't sync exercises between various devices or integration with Facebook. 4) Crashes when there are other apps open in pop-up view. I paid for premium, but didn't get premium features.
