About this tool
A stopwatch counts upward from zero, which is what you want for timing laps, workouts, cooking steps, experiments or anything else.
This one shows time to the centisecond, lets you record lap splits, and can pause and resume without losing your place. It tracks elapsed time against the real clock for accuracy, and runs entirely in your browser.
Frequently asked questions
How precise is the stopwatch?
It displays time down to centiseconds (hundredths of a second) and tracks elapsed time from the real clock.
Are lap times saved if I reload?
No. Laps are kept only while the page is open, so reloading clears them.
