How to Use the Countdown Timer

Using the countdown timer is simple and intuitive. Start by entering what you're counting down to in the "event name" field—this helps you stay focused on your goal. You can choose one of the quick preset buttons for common durations like 5 minutes or 25 minutes (perfect for Pomodoro sessions), or set a custom time using the hours, minutes, and seconds fields. Once you've set your time, click Start to begin the countdown. The large, easy-to-read display shows your remaining time, and a circular progress ring provides a visual representation of how much time is left.
