What is the difference between Pause and Stop?
Pause keeps the current run open so you can resume it. Stop finishes the run, saves it to recent history, and makes the next Start begin a new run.

GuideHow to use
- Select Start to begin timing immediately. Pause freezes the time, Resume continues it, and Stop finishes and saves the run.
- Select Lap while timing to record a segment. The table compares each split with its cumulative time.
- Switch between tenths and hundredths, or use the keyboard shortcuts when the page itself has focus.
- Copy lap results or download lap and recent-run history as CSV.
HelpFrequently asked questions
What is a lap split?
A split measures the time since the previous lap. The total beside it is the full elapsed time when that lap was recorded.
Does the stopwatch continue in another tab?
Yes, while the browser keeps the page available. The display uses timestamps when you return, so delayed background updates do not lose elapsed time.
How precise is an online stopwatch?
The display can show tenths or hundredths of a second, but browser, device, input, and screen-refresh delays mean it is not a certified timing instrument.
Can I save or export lap times?
You can copy the current lap summary or download lap and recent-run tables as CSV files.
