Online Countdown Timer

A countdown timer counts down from a specified time interval to zero. Unlike a stopwatch that counts upward, a timer lets you set an exact duration and alerts you when the time is up.

Countdown timers are useful for cooking, workouts, presentations, exams, meditation, and any task where you need to track remaining time. The visual progress ring gives you an at-a-glance view of how much time is left.

This free online timer plays an audio alert when it reaches zero and works entirely in your browser. No installation needed — it works on phones, tablets, and desktops.
