About the Online Stopwatch

A simple, accurate stopwatch you can use straight from your browser, with no app to install. Start and pause it as often as you like and it keeps counting to a hundredth of a second.

Record lap times to measure splits during workouts, experiments, cooking or games. Each lap shows both the split since the last lap and the total elapsed time.

Everything runs on your device, so it keeps ticking accurately as long as the tab is open.
