Frequently asked questions
Is the stopwatch accurate?
Yes. It measures the real elapsed time rather than counting frames, so it stays accurate to a hundredth of a second even if the display updates pause.
Is anything uploaded?
No. The stopwatch runs entirely in your browser with nothing uploaded, and it works offline.
Can I record lap times?
Yes. Press Lap while running to record each split and the running total, listed with the most recent at the top.
What happens if I stop and start again?
Stopping pauses the time and the button becomes Resume, so you can continue from where you left off without losing your laps.
Does it work on mobile?
Yes. It is fully responsive and works in any modern mobile browser.
