Online Stopwatch
freetoolonline.com Editorial TeamThis stopwatch runs entirely in your browser and times an activity to the hundredth of a second, with a lap list for comparing splits. There is nothing to download, install, or sign up for - click Start and the display begins counting up immediately.
Controls
- Start begins timing, and the display counts up in MM:SS.hh format.
- Lap records the current elapsed time into the list below without stopping the clock, so you can capture as many splits as you need while the stopwatch keeps running.
- Stop pauses the count; click Start again to resume from where you left off.
- Reset clears the display and the lap list back to 00:00.00 for a fresh run.
Common uses
Reach for it whenever you need a simple, no-fuss stopwatch without installing an app, for tasks like:
- Timing a workout set.
- Timing a cooking or study session.
- Rehearsing a presentation against the clock.
- Comparing lap splits during a run or a race.
Accuracy and background behavior
The display updates continuously in MM:SS.hh format while the stopwatch is running, driven by your browser's own clock rather than a server. The tab has to stay open while you time - closing it or navigating away stops the count, because there is no background process keeping it running.
Privacy
All timing runs locally on your browser's own clock, so there is no upload and no account. Nothing you time or record here is sent anywhere or stored, and it clears the moment you leave the page.

Frequently Asked Questions
What does Online Stopwatch do?
Times an activity to the hundredth of a second, with Start, Stop, Lap, and Reset controls and an ordered list of recorded laps.
Does clicking Lap stop the clock?
No - Lap only records the current elapsed time into the list below. The stopwatch keeps counting up so you can capture as many splits as you need.
Does the stopwatch keep running if I close the tab?
No. Timing runs only while the tab stays open - there is no background process, so closing the tab or navigating away stops the count.
What complementary tools work well alongside online stopwatch?
The countdown timer counts down from a duration you set, and the digital clock and analog clock both show the current time as a live display.
