About Countdown Timers

⏱️ How It Works

This countdown timer counts down from your specified time to zero. Simply set hours, minutes, and seconds, then hit Start. The timer runs in your browser — no app download needed.

When time’s up, you’ll hear an audio alert. The timer works even if you switch tabs, but keep the browser open.

🍅 The Pomodoro Technique

The 25-minute preset is perfect for Pomodoro sessions — a popular productivity method developed by Francesco Cirillo. Work for 25 minutes, then take a 5-minute break.

After four Pomodoros, take a longer 15-30 minute break. This technique helps maintain focus and prevents burnout during long work sessions.

💡 Common Uses

  • Cooking timers (boiling eggs, baking, steeping tea)
  • Workout intervals (HIIT, Tabata, rest periods)
  • Study sessions and focused work blocks
  • Presentation practice and speech timing
  • Meeting time limits and breaks
  • Power naps (10-20 minutes recommended)

⚠️ Keep In Mind

The timer requires your browser tab to stay open. Closing the tab or browser will stop the timer. For critical timing needs, consider a dedicated timer app.

Audio alerts may not play if your device is on silent or Do Not Disturb mode. Make sure your volume is up if you need the alarm.
