Online Stopwatch

Start, stop and record laps. The stopwatch keeps accurate time even if you switch tabs.

Online Stopwatch

00:00.00

Keyboard: Space starts and stops, L records a lap, R resets.

How to use the online stopwatch

  1. Select Start, or press Space.
  2. Select Lap, or press L, to record split times.
  3. Stop, copy your laps, or reset with R.

Accuracy

Time is measured with the browser’s high-resolution clock rather than by counting ticks, so it stays accurate when the tab is in the background or your device is busy. The display shows hundredths of a second.

Examples
