Frequently asked questions
What does a lap record?
Each lap shows the total elapsed time and the split time since the previous lap.
Is it accurate in a background tab?
The display can be delayed by browser or device policy, so use dedicated timing equipment for official records.
Can I save my laps?
Laps stay on screen while this tab is open and are not stored, so copy them elsewhere if you need them.
Is anything uploaded?
No. The stopwatch runs entirely in your browser.
