How to use the online timer
Rest periods matter as much as the work itself, and 158 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 158 seconds or timer for 158 seconds; both land here and start the same count.
Common questions
Does the timer work without an internet connection?
The page needs to load once, but the countdown itself runs locally in your browser, so a dropped connection partway through won't stop it.
Will the timer still run if my laptop goes to sleep?
No, if the device sleeps or the browser is suspended, the countdown pauses along with it, so keep your screen awake for an accurate result.
Is there a cost to use the timer?
No, it's free to use, with no registration, sign-up, or hidden limit on how many times you can run it.
Can I run more than one timer at once?
Yes, opening the page in separate tabs lets you track a few things at the same time, each counting down independently of the others.
