Online Stopwatch with Lap Timer
Precise online stopwatch with lap timer and split times. Start, stop, reset and record up to 100 laps. Works offline in your browser.
How to use
Start and stop
Click Start to begin timing. The display counts up in hundredths of a second. Click Stop to pause — the time is preserved so you can resume by clicking Start again. Reset clears everything back to zero.
Laps
Click Lap while the stopwatch is running to record a split time. Each lap shows the time for that lap individually and the running total. Useful for timing intervals, laps around a track, or any repeated activity where you want to compare individual sections.
