Stopwatch

Start, pause, and reset elapsed time. Record laps to compare splits — useful for workouts, cooking, or timing work blocks. Everything runs locally in your browser — your inputs are not uploaded to produce the result.

It displays down to milliseconds using your device clock. Each lap records the split since the previous lap and the total time from the start.

Elapsed time is based on wall-clock timestamps, so background tabs stay accurate. Tweak the inputs above to compare options, then copy or note the result you need.
