33 Second Timer with Alarm

A quick 33 second countdown for your phone or computer. Press Start, and a chime plays the moment it hits zero. Press Reset to go again.

Need to set a timer for 33 seconds? This one is ready to go. It's already set to 00:33, so all you have to do is press Start. You don't need to type anything in, install an app or create an account.

As it counts down, the ring around the clock gets shorter so you can see the time left without reading the numbers. The countdown also shows in your browser tab, so you can work in another tab and still see it. When it reaches zero, a chime plays. Check that your sound is on.

People use a 33 second timer for things like plank holds, breathing exercises, speed rounds in class, sprint intervals, or timing each quadrant while you brush your teeth.

Frequently Asked Questions

Can I repeat a 33 second timer over and over?

Yes. When the chime plays, press Reset and then Start. It takes two taps, which makes it handy for intervals and practice rounds.

Will the alarm still go off if I switch tabs?

Yes. The timer goes by your device's clock, so it doesn't slow down when the browser puts the tab in the background. Keep the tab open and your volume up. On some phones the browser can't play sound while the screen is locked, so it's safer to keep the screen on.

Can I change the time or make it fullscreen?

Yes. Tap Edit to set any hours, minutes and seconds you like, or tap Fullscreen to show a big countdown on a classroom board, TV or kitchen tablet.

What is a 33 second timer good for?

33 seconds works well for plank holds, breathing exercises, speed rounds in class, sprint intervals, or timing each quadrant while you brush your teeth. Doing intervals? Press Reset and then Start after each round.

Can I share this timer or put it on my website?

Yes. Tap Share to copy a link (it includes any custom time you set), or copy a short code that embeds the timer on your own website or classroom page.
