Quick start

A clean timer that does one job well: no signโ€‘up, no ads over the clock, no sounds downloaded from elsewhere. The countdown keeps accurate time even when you switch tabs, shows the remaining time in the tab title, and plays an alarm generated by your browser when time is up.

Why this tool is safe

This page loads no tracking scripts, and its security policy forbids it from sending data to other servers. The work happens in your browser's memory and is gone when you close the tab.

Frequently asked questions

Will the alarm sound if I switch tabs?

Yes, as long as the page stays open and your device is not muted. On phones, keep the screen on, because many phones pause web pages when the screen locks.

How accurate is it?

Time is measured with the browser's highโ€‘resolution clock and not by counting ticks, so it stays accurate even if the page is busy or in the background.

Does it work offline?

Yes. Once the page has loaded it needs no internet connection at all.
