Interval Timer (HIIT)

A repeating interval timer for HIIT, Tabata, and circuit workouts. It alternates a work period and a rest period for a set number of rounds, announcing each switch with a beep so you can keep your eyes off the screen.

Set your work and rest lengths and the number of rounds, then start. The round counter shows exactly where you are, and Skip jumps to the next interval if you finish early.
