Tabata timer

How to use the Tabata timer

Tabata is 20 seconds of hard work and 10 seconds of rest, eight times over: four minutes in all. The timer opens set up that way, so press Start and go when the countdown ends. The screen is green for work and amber for rest, and three short beeps lead into each change.

Change the work, rest or rounds for a longer variation, or pick 30/15 or 40/20. List movements, one per line, to alternate between them from round to round: the current one shows under the clock and the next one during the rest.

Common questions

How long is a Tabata?

Four minutes less the last rest: eight rounds of 20 seconds of work and 10 seconds of rest come to 3 minutes 50 seconds, because the timer stops after the last work period.

Does it keep time if the screen locks or the tab is in the background?

Yes. The time comes from the clock rather than from counting, so it is right when you come back. Phones silence a web page once the screen locks, so the timer keeps the screen awake while it runs.

Is the timer free?

Yes. There are no ads, no account and nothing to install. It is made by one person, alongside the WOD Generator app.
