What is an interval timer?

An interval timer alternates fixed periods of work and rest. It is used for HIIT, Tabata, circuit training and any workout built around timed rounds.

How do I set up a Tabata workout?

Tabata is eight rounds of 20 seconds of work followed by 10 seconds of rest. Set work to 20 seconds, rest to 10 seconds and rounds to 8.

Does the interval timer make a sound?

Yes. A short tone plays at the end of every work and rest interval so you can follow the workout without watching the screen.
