Countdown Timer
A free online countdown timer with Pomodoro presets, start/pause/reset, and an alarm when time is up.
Frequently Asked Questions
Does the timer keep running if I switch tabs?
Yes. The countdown continues running in the background. When it reaches zero an alarm sounds, so you will be alerted even if you are on another tab or app.
What is the Pomodoro Technique?
It is a time-management method that breaks work into focused 25-minute intervals separated by short 5-minute breaks, with a longer break after about four rounds. Use the built-in presets to follow it.
Can I set a timer for more than an hour?
Yes. Enter any number of minutes — for example 90 minutes — and the timer will display hours, minutes, and seconds automatically.
Will it make a sound when the time is up?
Yes. A clear alarm tone plays when the countdown reaches zero and the display turns red. Make sure your device volume is on.
Do I need to install anything?
No. The timer runs entirely in your web browser with no download, signup, or permissions required.
Countdown Timer — Free Online Timer with Pomodoro Presets
A countdown timer is one of the simplest yet most useful tools for staying focused and on schedule. Whether you are studying with the Pomodoro Technique, timing a workout, cooking, running a meeting, or giving yourself a hard stop on a task, this online timer counts down to zero and alerts you the moment time is up — no app to install and no account to create.
Set any duration in minutes and seconds, or tap a preset to start instantly. The built-in Pomodoro presets follow the classic productivity method: a 25-minute focus session followed by a 5-minute short break, with a longer 15-minute break for after several rounds. Studying or working in timed intervals like this is proven to reduce procrastination and mental fatigue, because a visible deadline keeps your attention on a single task instead of letting it drift.
The timer gives you full control while it runs. Start begins the countdown, Pause freezes it exactly where it is so you can resume later, and Reset returns it to your chosen duration. When the timer reaches zero, the display turns red and a clear audible alarm plays so you do not miss it even if you have switched to another tab or stepped away from the screen.
Everything runs entirely in your browser. There is no server involved, nothing is logged, and the timer keeps ticking accurately in the background. Common uses include Pomodoro study and work sessions, timing presentations and speeches, interval training and HIIT workouts, cooking and baking, board-game turns, meditation, and giving children a fair, visible countdown for screen time or chores.
