A timer that keeps its promise

Many online timers drift or stay silent when the tab is in the background, because browsers slow down hidden pages to save battery. This timer works differently: when you press Start, the alarm is scheduled in the sound system of your browser for the exact end time, so it rings on time even if you are in another tab.

The end time is also saved on your device. If you close the tab by accident or reload the page, the countdown is still running when you come back.

Made for real use

Use full screen mode in a classroom, a workshop or a meeting so everyone can see the time left. Add a minute with one click when you need a little more, and use the keyboard: space starts and pauses, R resets, F switches to full screen.

While the timer runs, your screen stays on, so a laptop on the kitchen counter will not go to sleep in the middle of a recipe.
