What is an online timer?

An online timer is a simple countdown tool that runs directly in your browser. You set a duration (for example 10 minutes), press start, and the timer counts down to zero. When the countdown finishes, the timer alerts you with a sound so you don’t miss it. Clock7 Timer is designed to be fast, distraction-free, and easy to use on desktop and mobile.

Quick presets for common countdowns

Most people set the same durations repeatedly. That’s why this timer includes one-tap presets for 1 minute, 5 minutes, 10 minutes, 15 minutes, 30 minutes, and 1 hour. Tap a preset and your countdown starts immediately—perfect for breaks, cooking, workouts, study sessions, meetings, and timeboxing.
