What is an online stopwatch?
An online stopwatch counts up from zero right in your browser, so you can time a workout, a race, a presentation, or pretty much any interval without needing a physical watch. This one shows hundredths of a second and lets you keep track of laps while it’s running.
There’s nothing to download or install. Just start, pause, or reset the stopwatch from this page. Your laps only stick around for this visit.

FAQ
How precise is this stopwatch?
It uses your browser’s high-resolution timer and displays hundredths of a second. That’s quite accurate for a simple stopwatch.
What does Lap record?
Lap records the elapsed time at that moment. The main stopwatch keeps running, and your newest lap appears at the top.
Does the stopwatch keep running if I switch tabs?
Yes. Elapsed time is calculated from a high-resolution clock, so switching tabs won’t throw it off. The display may freeze when the tab is in the background but catches up when you return.
Are laps saved if I leave the page?
No—your time and laps are only stored for your current visit. Nothing is saved once you leave, keeping things simple and private.
Do I need to install anything?
Nope! Just open the page and start the stopwatch—no download, account, or extra steps needed.
