"Interval Exercise" is an app to keep track of your intervals in your training program.
Type in warm up time, 1-3 different intevals, how many repetition and maybe a cool down time.
The app will tell you, when your warm up time is finish, beep you the different intervals with a pleasureble beep, and tell you, when you are finish.
For now, the app can't run in lock screen mode, but you're given the choise to turn off lock screen.
The app is developed by AIKON, www.aikon.dk
