Interval Training Timer

Easy to use interval training timer with six presets.
Use it for your gym sessions, training at home, HIIT, isometric exercises or any other type of time based training.
The app is built with buttons, big enough to be used with tired fingers or when buttons seem really small. All presets can be loaded on the main screen, so you don't have to change screens between exercises.
