A free online WOD clock

How to use each mode

Clock shows the time of day in 24-hour format. Leave it on a spare screen as a wall clock between classes.

For Time counts up from zero. Set a time cap in minutes if your workout has one, or leave it at 0. When you finish, press Pause, then Finish, and the clock holds your time. With a cap, it stops at the cap. See the For Time guide for scoring.

AMRAP counts down the minutes you set. Work through your rounds until it reaches zero, then note rounds and reps. The AMRAP guide covers partial rounds.

EMOM starts a new round on every interval. Choose the interval and the number of rounds; the clock counts down each one and shows which round you are on. More in the EMOM guide.

Tabata defaults to 20 seconds of work and 10 seconds of rest for eight rounds. Change the work, rest and rounds for other interval sessions. The clock stops at the end of the last work interval. See the Tabata guide.

Setting it up in the gym

1. Choose the mode and check the settings.
2. Tap the Sound button to turn the beeps on. Browsers keep sound off until you tap.
3. On a laptop or a TV connected to one, press Fullscreen so the digits fill the screen.
4. Press Start or the space bar. The 10-second count-in beeps at 3, 2 and 1, then goes.

Three short beeps sound before each change of round or phase, and a longer beep marks the start. Work shows in green and rest in red, so the room can read the phase at a glance. On a phone, turn it sideways for bigger digits.
