Online EMOM timer

A beep at the top of every minute, or every 2 or 3, free in your browser

Interval timer

Ready when you are

01:00

Keep this tab open and in front: browsers can slow down timers in background tabs. The Cero app keeps going with your screen locked, on your Apple Watch and in the Dynamic Island.

How to use it

  1. Pick a preset: EMOM 10 or EMOM 20 beep every minute, E2MOM every 2 minutes and E3MOM every 3.
  2. Press Start. When the minute begins, do your reps, then rest for what’s left of it.
  3. Each round is one minute (or two, or three), and the rest is set to 0: your rest is whatever you don’t use.
