About this tool
The countdown timer is a clean, reliable online timer that rings when time runs out. Set any duration in hours, minutes and seconds, or tap a quick preset and go.
It is perfect for cooking, studying with the Pomodoro technique (try the 25-minute preset), workouts, presentations, games and timeboxing your tasks. The timer stays accurate even if your device sleeps, and a gentle three-tone alarm lets you know the moment it finishes.
Frequently asked questions
Will the timer keep accurate time if I switch tabs?
Yes. It tracks the real end time rather than just counting ticks, so it stays accurate even if the tab is in the background or your screen briefly sleeps.
Is there an alarm sound?
Yes — a gentle three-beep chime plays when the countdown finishes. (Browsers need a tap on the page first before they’ll allow sound.)
Can I use this as a Pomodoro timer?
Definitely — tap the 25-minute preset for a focus session, then a 5-minute preset for your break. It’s a simple, distraction-free Pomodoro setup.
Do I need to install anything?
No. The timer runs entirely in your browser with no downloads, accounts or permissions required.
