FAQs

Is this stopwatch free?

Yes. It is completely free with no sign-up and no limits on how long or how often you use it.

How accurate is the stopwatch?

It measures time using your browser’s clock and displays hundredths of a second. Actual accuracy depends on your device and browser.

Does it keep running if I switch tabs?

The timer keeps counting in the background, but most browsers slow down background tabs, so the display may update less often until you return.

Is my timing data stored anywhere?

No. The stopwatch runs entirely in your browser with JavaScript and nothing is transmitted or saved.
