Frequently asked questions
Which keyboard shortcuts are available?
Space starts and pauses, L records a lap, R resets and F toggles full screen.
Does it keep running if I reload the page?
Yes. The start time is saved in your browser, so the stopwatch continues from the right time after a reload.
How accurate is it?
It uses the clock of your device, so the elapsed time does not drift even if screen updates are delayed.
