Stopwatch

The online stopwatch lets you measure elapsed time with precision. You can start, pause, and reset the stopwatch, and record laps and splits to analyze segments.

Yes, the stopwatch is completely free—no accounts, no subscriptions, no hidden fees.

Lap time is the duration of each segment between lap presses. Split time is the cumulative time from the start to the current lap. Both help you compare performance over multiple segments.

The stopwatch runs entirely in your browser using high-resolution timing. It provides accurate millisecond-level tracking depending on your device and browser.

Any modern browser on Windows, Mac, Linux, iOS, or Android. No installation required.

All timing happens locally in your browser. No data is uploaded to a server.
