What does the Stopwatch do?

Start, pause and resume with one button, and record laps to capture each segment’s time and the running total. Timing uses the browser’s high-resolution clock, so accuracy is not affected by how often the screen refreshes.

On a computer press Space to start or pause, L for a lap and R to reset. Download laps as CSV to keep a record.

How to use the Stopwatch

  1. Click Start (or press Space).
  2. Click Lap (or press L) to record splits.
  3. Pause and resume as needed.
  4. Download laps or Reset.
