A timer and stopwatch in your browser

You don't always have a kitchen timer or stopwatch to hand, but you usually have a browser tab. This tool counts down to zero with an alarm, or counts up as a stopwatch, which covers cooking, workouts, timed tasks, and games. It keeps running in the tab so you can glance back whenever you need the time.

How to use it

  1. Set a countdown duration, or start the stopwatch.
  2. Let it run — an alarm sounds when a countdown reaches zero.
  3. Pause, resume, or reset as needed.

Where it helps

Questions people ask

Will it alarm if the tab is in the background? It keeps counting, and the alarm fires when due; keep the tab open and sound enabled so you hear it.

Does it need the internet? No — it runs in your browser once loaded.
