Multiple Stopwatches
Run several named stopwatches at once, each controlled on its own.
Each stopwatch runs on its own — start, pause and reset them independently. Names are saved in your browser.
How to use the multi stopwatch
- 1
Each stopwatch starts paused at zero — press Start on whichever ones you need.
- 2
Give a stopwatch a name (a runner, a lane, a task) so you can tell them apart.
- 3
Start, pause and reset every stopwatch independently — they do not affect each other.
- 4
Add another stopwatch any time, or remove ones you are finished with.
- 5
Reset all of them at once with the Reset all button when you start a fresh session.
Tips & tricks
Running several stopwatches at once is the easy way to time things in parallel — a few runners on a track, stations in a workout, or competing teams in a classroom game. Each one keeps its own accurate time.
Every stopwatch uses the same high-resolution timing as the single stopwatch, so none of them drift, even when you leave the tab in the background and come back later.
Your set of stopwatches and their names are remembered in your browser, so if you close the tab and return, your setup is still there.
Frequently asked questions
How many stopwatches can I run at once?
You can run several at the same time — enough for tracking a small group of runners, workout stations or teams. Each is controlled completely independently.
Do the stopwatches affect each other?
No. Starting, pausing or resetting one stopwatch has no effect on the others. They each keep their own time.
Can I name each stopwatch?
Yes. Give each one a label — a person, a lane, a task — so you can tell at a glance which time belongs to what.
Are the multiple stopwatches still accurate?
Yes. Each one is measured against the browser's high-resolution clock, so they stay accurate over long sessions and survive the tab being in the background.
Is my setup saved?
Your stopwatches and their names are saved in your browser, so your setup is waiting for you when you return. Nothing is uploaded.
Is it free?
Yes, completely free with no sign-up and no limits.
