Frequently Asked Questions

?Can I save or export my lap times?

Currently, you can copy the lap list to your clipboard or take a screenshot. Export to CSV is planned for a future update.

?Is this stopwatch really free to use?

100% free with no registration, no ads overlays, and no hidden limits. Use it as long as you need, as often as you like.

?How accurate is this online stopwatch?

It uses your device's system clock to display time with millisecond precision, typically accurate to within a few milliseconds per second.

?Does it work on mobile phones and tablets?

Yes. The stopwatch is fully responsive and works on any modern smartphone, tablet, or desktop browser with a touch-friendly interface.
