Online stopwatch
Start instantly, record lap splits and keep elapsed time clear to one hundredth of a second.
Stopwatch controls
Elapsed time
- Lap appears while the stopwatch runs
- Reset and full screen are available under More options
- Lap results show both split time and total elapsed time.
- Recorded laps can be downloaded as a CSV file after the stopwatch starts.
How to use the online stopwatch
- Press Start when the activity begins.
- Choose Lap whenever you need to record a split without stopping the clock.
- Pause to review the result, then reset or export the recorded laps when available.
Useful precision, without a control panel.
- Record running laps, practice rounds, presentation sections, experiments, or any repeated effort where both split and total time matter.
- Laps remain on this device, the newest result stays easy to scan, and reset is always deliberate rather than automatic.
