About this tool
Sometimes you just need a stopwatch without installing an app or digging through your phone’s clock menus. This one runs right in the browser: big readable digits, start/pause with a single button, and lap recording for splits. Timing is based on your device’s high-resolution clock rather than counting timer ticks, so it stays accurate to the hundredth of a second even if the browser tab is briefly busy — good enough for workouts, cooking, speeches, and lab experiments.
Each lap records two numbers: the split (time since the previous lap) and the total elapsed time, which is exactly what coaches and presenters usually want side by side. Pausing freezes the clock without losing your laps, and reset clears everything for the next run. The display keeps updating while the page is visible; switching tabs may throttle the visual refresh on some browsers, but the underlying elapsed time stays correct. Like everything on this site, it works offline once loaded and sends nothing anywhere.
