TimeBuddyPro's free online stopwatch measures elapsed time with hundredth-of-a-second precision. Press start, pause and resume with one click, record unlimited laps to compare split times, and reset instantly when you're done. Everything runs in your browser — no sign-up, no download, and it keeps timing accurately even when you switch tabs.
How to use the stopwatch
Press Start to begin timing. Press Pause to freeze the clock without losing your time, then Resume to continue. Use Lap while the timer is running to record a split — each lap shows both the split time and the total elapsed time. Reset clears everything back to zero.
Lap times, fastest and slowest highlighted
Every lap you record appears in the lap table below the timer. Once you have two or more laps, the fastest split is highlighted in green and the slowest in orange, so you can spot your best and worst segments at a glance — ideal for runners, swimmers, and circuit training.
When to use an online stopwatch
An online stopwatch is perfect whenever you need hands-free, precise timing: tracking run splits, timing workout rounds, rehearsing presentations and speeches, running classroom activities, timing study sprints, or measuring how long everyday tasks actually take.
Accurate, private, and free
The stopwatch calculates elapsed time from your device's high-resolution clock, so it stays accurate even if the tab is in the background. Your times never leave your browser — nothing is uploaded or stored on a server. And it's completely free, with no account required.
Frequently asked questions
Is this online stopwatch free?
Yes. The TimeBuddyPro stopwatch is completely free with no sign-up, no download, and no usage limits.
Will the stopwatch keep running if I switch tabs?
Yes. Elapsed time is calculated from your device's clock, so switching tabs or minimizing the browser does not pause or slow it down.
How accurate is the stopwatch?
It displays time to the hundredth of a second (centiseconds), using your browser's high-resolution timer. That's plenty for sports, workouts, and presentations.
Can I record lap times?
Yes — press Lap (or the L key) while timing to record unlimited splits. Your fastest and slowest laps are highlighted automatically.
