About the Countdown Timer
An online countdown timer counts down from a time you set and rings when it reaches zero. This free timer runs entirely in your browser: set the hours, minutes and seconds (or tap a preset like 5 or 10 minutes), press start, and watch the large, easy-to-read display count down. When it finishes, a sound plays and a desktop notification pops up so you never miss it.
It is handy for cooking, workouts, study sessions, presentations, tea and coffee, meditation, exams and any task where you want a clear time limit. You can pause and resume, reset, and pick from quick presets. Nothing is installed and nothing is uploaded — the timer works instantly and remembers your last setting.
