About the Countdown Timer
The countdown timer counts down from any duration you set — seconds, minutes or hours — and plays a clear alarm when it reaches zero. Choose a quick preset or enter a custom time, pick from several alert sounds, and watch the progress ring empty as the seconds tick away. It is handy for cooking and baking, HIIT and rest intervals, Pomodoro study sessions, presentations, exams and keeping kids on track. The screen stays awake while the timer runs, the remaining time shows in your browser tab, and everything works on phones, tablets and desktops — with no app to install.
