Choose a countdown for the task

A countdown measures the time left from a duration you set. A stopwatch measures elapsed time from zero. Use a clock alarm when you need an alert at a particular time of day.

Keep the page open and test sound before relying on a browser alert. Muted audio, a sleeping device or a closed tab can stop the alert from sounding when expected.

How to use this tool

  1. Set the duration for the task.
  2. Check the alert settings before starting.
  3. Start the countdown and use its controls to pause or reset.

Example

A task with a 7 minute allowance needs a 7 minute countdown. If you do not know the duration in advance, measure it with a stopwatch instead.
