About Stopwatch

Start, pause and resume with a button or the Space key, and record laps with L. Each lap shows its own time and the running total, with the fastest and slowest laps marked, and the laps can be copied or downloaded as a CSV file.

Time is measured from the moment you pressed Start using the browser's high-resolution clock, not by counting ticks, so it stays accurate in a background tab. It is a web stopwatch: fine for training, cooking or timing a task, not for officially timed events.

How to use it

  1. 1Press Start or the Space key.
  2. 2Press Lap (or L) at the end of each lap.
  3. 3Press Pause to stop the clock and Reset (or R) to clear it.
  4. 4Copy the laps or download them as CSV.
