Stopwatch & Lap Timer
The Stopwatch & Lap Timer is a simple, accurate stopwatch you can use right in your browser tab -- no app download needed. Start, stop, record laps, and reset whenever you like.
Lap times are listed with the most recent lap at the top, so you can track splits during a workout, a race, or any timed activity.
How to Use the Stopwatch & Lap Timer
- Open the Stopwatch & Lap Timer.
- Click Start to begin timing.
- Click Lap at any point to record a split without stopping the clock.
- Click Stop to pause, or Reset to clear everything and start over.
Frequently Asked Questions
How accurate is this stopwatch?
It displays time down to a tenth of a second, driven by your browser's own timing functions, which is accurate enough for most casual timing needs.
Do lap times reset the total time?
No, recording a lap just logs the current elapsed time in the list -- the stopwatch keeps running until you press Stop.
Does the timer keep running if I switch to another tool?
No, navigating away from the Stopwatch stops and clears its running timer, so come back and start again if you need to keep timing.
