Stopwatch · Precision.
A precise stopwatch with lap tracking. Hit Start to begin timing, record laps as you go, and see your fastest and slowest splits highlighted automatically.
Last updated recently. The stopwatch display runs in the browser. Server-rendered copy explains the measurement model and avoids claiming persistence beyond the current tab session.
Smooth 60fps ring, spring-press buttons, laps slide in.
Start the stopwatch, record laps while it runs, and reset it back to zero when you are done.
Click the Start button. The progress ring begins to fill and the digits count up in minutes, seconds, and hundredths of a second. Click the same button again to pause, and once more to resume.
While the stopwatch is running, click Lap to capture the current elapsed time. Each lap slides into the list below the controls; the most recent eight laps are kept for the session.
Click the reset button to stop the stopwatch, clear the elapsed time, and remove every recorded lap so you can start a fresh measurement.

WHY IT MATTERS
Stopwatch intent looks simple, but the winning page is the one that feels reliable the moment it opens. People do not want to wonder whether the tab will drift, whether laps will be visible, or whether the display is precise enough for training, classroom, or production-floor timing.
That is why this page keeps the explanation, related tools, and lap-oriented FAQ around the live widget. The tool itself is interactive, but the surrounding copy is server-rendered so the page still explains what it does before JavaScript finishes hydrating.
