Online Stopwatch

A free online stopwatch that counts up in minutes, seconds, and hundredths. Start, stop, and record laps — handy for timing workouts, cooking steps, study sprints, or anything you need to measure.

The Lap button freezes a split without stopping the clock, so you can capture each interval and compare them afterwards. Everything runs locally in your browser.

How it works: press Start to run the clock, Lap to record a split without stopping, and Reset to clear it. The stopwatch times against the real clock, so it stays accurate even in a background tab.
