Interval Fitness Timer

Interval Fitness Timer is a highly customizable timer application for HIIT, circuit and any other kinds of interval workouts.
Every round of your workout, as well as every exercise within a round, can be individually customized or simply kept identical to perfectly match your workout preferences.
In addition, you can create any number of timers and store each of them to reuse whenever you want. This way, you wont have to keep resetting a single timer when you do several different interval workouts, each with its own requirements.
