How to use the Countdown Timer

  1. Enter hours, minutes and seconds, or tap a preset like 5 or 10 minutes.
  2. Press Start.
  3. Pause or reset whenever you need.
  4. An alarm beeps and the tab title changes when time is up.

What does this tool do?

The timer tracks the actual end time rather than counting ticks, so it stays accurate. The alarm is generated by your browser, with no sound files to download.

Why use it?

  • Cooking, exams, presentations and breaks.
  • Quick presets.
  • Full-screen view for classrooms.

Tip

Keep the tab open. Some phones pause background tabs to save battery, which can delay the alarm.
