A clean stopwatch for workouts, cooking, presentations and anything else you need to time. Laps are recorded to the millisecond and can be copied out as text.
When to use it: workouts, cooking, studying and timing anything with laps.
Frequently asked questions
Does the stopwatch keep running if I switch tabs?
Yes. It is based on a timestamp rather than counting ticks, so it stays accurate even if the browser throttles background tabs.
What is the difference between a lap and the total?
A lap records the moment you press it while the stopwatch keeps running, so you can compare intervals — like laps on a track.
Can I use it for interval workouts?
Yes — press Lap at each set change and read your interval times from the lap list afterwards.
Does it keep running if I close the tab?
No — closing the page stops it. Keep the tab open; it happily runs in the background while you work.
I need to count down instead — which tool?
The Countdown Timer. The stopwatch only counts up, by design.
Is my timing data stored?
No — times live in the open page only and are gone when you leave. Nothing is recorded.
