Free Online Loud Online Timer with Alarm

Need a timer you can hear from across the room? Use our Loud Online Timer with synthesized high-frequency alarm.

This is a loud online timer with alarm that opens ready to use. It's preset to 10 minutes (10:00), and you can change the time with Edit if you need something different.

The ring around the clock gets shorter as time runs down, and the time left also shows in your browser tab. When it reaches zero, a chime plays, so check that your volume is up.

Frequently Asked Questions

What time is the loud online timer with alarm set to?

It opens at 10 minutes (10:00). Tap Edit to set any other length, from a few seconds up to several hours.

Will the alarm still go off if I switch tabs?

Can I use it fullscreen?

Yes. Tap Fullscreen for a large, easy-to-read countdown on a TV, tablet or classroom screen.

Do I need to download anything?

No. It runs in your browser on iPhone, Android, Mac, Windows and Chromebook, and it's free with no sign-up.

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.
