Turning this on asks your browser for permission once.

The countdown is anchored to a finish time, so it stays exact even if the tab is in the background. Press Test sound once so the browser lets audio play. Space starts and pauses, L takes a lap, R resets.

A timer for a room full of people needs to be readable from the back and calm when it ends. Press Full screen and the countdown fills the display, with everything else hidden.

The shrinking ring gives students a sense of time passing without them having to read the numbers, which is often the more useful signal during independent work.

A free online timer, stopwatch and countdown clock that runs entirely in your browser. No account, nothing to install.

It keeps working offline once loaded, and you can add it to your home screen like an app. Your settings stay in your own browser.

Press Voice control and allow microphone access, then speak normally. Your speech is handled by your browser's own speech service, and nothing is stored by this page. Allow the microphone once and switch this on once, and it stays on as you move around the whole site, in this tab or a new one. It switches itself off after an hour of not being used. The button always shows whether it is listening, and tapping it stops it for good.

  • "set a timer for ten minutes" starts a ten minute countdown
  • "five minutes thirty seconds" any duration, in hours, minutes or seconds
  • "half an hour" and "a minute and a half" are understood too

Can I make it silent?

Yes. Set the alarm to Silent and the screen flashes instead of making a sound, which suits exam conditions and quiet reading time.

Can I run timers for different groups at once?

Yes. Set a duration, give it a group name in the Label field, then press Add another timer. Each one runs and can be paused independently.
