Questions
Does the stopwatch keep running if I switch tabs?
Yes. Time is calculated from the moment you pressed start, so it stays correct in the background and even after a page reload.
How do I record a lap?
Press Lap or the L key while the stopwatch is running. The fastest lap is marked in orange.
Can I save my laps?
Open Share and download to get a lap report as PDF, a CSV table or an image card.
Which keyboard shortcuts work?
Space starts and pauses, L records a lap, R resets when paused and F switches to full screen.
