How it works

  1. Set the round time, the rest time and the number of rounds.
  2. Tap Start. You see which round is running and how many are left.
  3. Orange is the round, teal is the rest; the last three seconds beep down.
  4. Reset to run the same session again.

Frequently asked questions

What do you use a round timer for?
For anything that runs in rounds: boxing training, MMA, grappling, but also circuits where you work and rest a fixed time per station.
What is the difference with an interval timer?
Nothing essential: it is the same engine. Only the defaults differ, here the classic 3-to-1 ratio of a round.
Do I get a bell at the end of the round?
In the browser you hear a beep. In the app the rounds are spoken out loud and your music keeps playing.
