FAQ

Does the stopwatch keep running if I switch tabs?

Yes. The stopwatch tracks real elapsed time, so it stays accurate even if you switch tabs or the browser tab is in the background.

How precise is the stopwatch?

It measures time down to the hundredth of a second (centiseconds), which is precise enough for workouts, cooking, races, and everyday timing.

Can I record multiple laps?

Yes. Press Lap as many times as you need while the stopwatch is running. Each lap time is listed with the most recent at the top.

Do I need to install anything or sign up?

No. The stopwatch runs entirely in your browser — no installation, account, or download required.
