Set the timer to 168 seconds

00:00:00

How to use the online timer

Rest periods matter as much as the work itself, and 168 seconds is a common gap between rounds in a lot of interval training. Start it the moment you finish a set, use the time to catch your breath and grab some water, and get ready to go again as soon as it counts down to zero. Watching a clock never feels as precise as letting the timer call it.

Press Start and it gets going immediately, no sign-up screen or settings menu standing in the way. The one thing to remember is that it counts down inside this browser tab, so it needs to stay open rather than closed or replaced by another site if you want an accurate result. A sound plays once the time is up, which is your cue that whatever you were timing is done.

A mechanical timer needs to be wound and a phone timer needs the phone unlocked, but this one just needs the page you already have open. It sits inside your browser, ready whenever you are, and it's the same tool whether you're on a laptop or a tablet in the kitchen. Free, with nothing to install or sign into, it's built to get out of your way and count. People type this as set timer 168 seconds or timer for 168 seconds; both land here and start the same count.

Common questions

Will the timer keep running if I close the tab?

No. Closing the tab or the browser stops the countdown, so leave it open until the timer finishes.

Can I use the timer on my phone?

Yes. It works in any mobile browser, though the tab still needs to stay open rather than sitting behind other apps for a reliable count.

Does the timer make a sound when it finishes?

Yes, an alarm plays once it reaches zero, provided your device's volume is turned up and the tab hasn't been muted.

Can I pause the timer partway through?

Yes, pause and resume are both available, so you can stop the count if you're interrupted and pick up again exactly where you left off.
