About this tool
A straightforward stopwatch for timing anything — workouts, presentations, cooking, or games — accurate to the hundredth of a second. Press "Lap" while it's running to record split times without stopping the clock.
Frequently asked questions
- Does the stopwatch keep running if I switch tabs?
- Yes — timing is based on real elapsed time (not a simple tick counter), so switching tabs, minimizing the window, or the browser throttling background timers won't cause the displayed time to drift or fall behind.
- How many lap times can I record?
- As many as you like during a single run — each lap shows both its own split time and the total elapsed time at that point.
- What happens if I press Reset while it's running?
- Reset stops the stopwatch, clears the elapsed time back to zero, and clears all recorded laps.
