⏱️ Stopwatch
A precise online stopwatch with laps, showing minutes, seconds and hundredths.
About this Stopwatch
This online stopwatch measures elapsed time to the hundredth of a second and keeps a list of your laps with both the total time and each individual lap time. It uses your device clock for timing, so it stays accurate even if the display refresh pauses, and it works for sports practice, cooking, study sessions, experiments and speed tests without installing any app.
How to use it
- Press Start to begin timing.
- Press Lap at each split point to record a lap.
- Press Pause to stop the clock, then Start to resume.
- Press Reset to clear the time and the lap list.
Example
Start the stopwatch, press Lap after one round of exercise at 00:45.30 and again at 01:32.10: the second lap time shows as 00:46.80.
Frequently asked questions
How accurate is the stopwatch?
Timing is based on your device clock and shown to hundredths of a second, which is plenty for training and everyday timing.
Can I pause and resume?
Yes. Pause freezes the total, and Start continues from exactly where you stopped.
What is the difference between lap time and total?
Total is the time since you first pressed Start; lap time is only the time since the previous Lap press.
