Free round interval timer for workouts, coaching, and training

This free round timer is built for fast training use: choose a preset, press start, and run clean intervals with audible alarms. It works for boxing, kickboxing, Muay Thai, HIIT, circuit training, home workouts, classes, and conditioning blocks.

You can also build custom intervals with prep time, work time, rest time, and multiple rounds. The setup saves in your browser so your usual workout timer, class timer, or coaching timer is ready when you come back.

Common uses

  • 1 minute rounds with 20 seconds rest
  • 3 minute boxing rounds with 1 minute rest
  • Kickboxing, Muay Thai, and sparring intervals
  • HIIT, circuit training, and conditioning finishers
  • Private lessons, small groups, and home workouts

Can I use this for boxing or kickboxing rounds?

Yes. Use a quick preset like 3:00 x 1:00 or build your own round and rest timing.

Can I mute the alarm?

Yes. Use Sound on or Sound muted, and test the alarm before class starts.

Does it save my setup?

Yes. Your current interval list saves in the browser on the same device.
