Timed in this browser. Nothing is sent anywhere.

Display updates ~20 times a second; the clock itself counts wall time, so a hidden tab keeps counting accurately. Nothing is stored after you leave the page.

How to use

  1. Press start.
  2. Tap lap at each split.
  3. Stop and read the lap table.

What it supports

Counts real elapsed time even when the display throttles in a hidden tab. Nothing is saved after you leave the page.
