What is an interval timer?

What is an interval timer? An interval timer alternates between periods of work and rest for a set number of rounds, signalling each change. It is used for circuit training, HIIT and any activity broken into repeated blocks.

  1. Set preparation, work and rest times in seconds.
  2. Choose the number of rounds and an optional cooldown.
  3. Press Start. Three beeps sound before each phase change.
  4. Use Skip to jump to the next phase.

Frequently asked questions

Is there rest after the final round?

No. The last work interval goes straight into the cooldown (or finishes), because a trailing rest period is not useful.
