What this tool does
Use this stopwatch to track elapsed time in your browser with start, pause, lap, and reset controls. The timer runs locally on your device and restores its last saved state after a refresh.
How laps work
- Each lap stores the total elapsed time at the moment you record it.
- The laps table shows both the split for that lap and the cumulative total.
- Export the lap list as CSV if you want to review or share the timings elsewhere.
Good to know
- The display updates in hundredths of a second.
- Stopwatch data is stored in your browser’s local storage and is not uploaded to a server.
- Reset clears the elapsed time and all saved laps for this browser.
