A lap records the elapsed time at that moment without stopping the stopwatch, so you can capture splits — useful for running intervals or repeated tasks.

Can I pause and resume the stopwatch?

Yes. Stop pauses the count and Start resumes it from the same time. Reset clears everything.

Does it keep timing if I switch tabs?

Yes, timing continues while the tab is open. Because it uses the real clock, the elapsed time stays correct.

Is the stopwatch free?

Yes — free, no sign-up, no ads to use it, and it runs entirely in your browser.

What is the difference between a stopwatch and a timer?

A stopwatch counts up to measure elapsed time; a countdown timer counts down from a set time and alerts you at zero.
