About Online Timer

The Online Timer lets you count down from any duration with quick presets ranging from 1 minute to 1 hour, or type a custom time in minutes and seconds. The circular progress ring provides a clear visual indicator of remaining time at a glance.

Use it for cooking, workouts, Pomodoro study sessions, classroom activities, meeting time-boxes, or any task that needs a timed boundary. The audio alert ensures you never miss the end of your timer, even if you switch tabs or step away from the screen.

The countdown is calculated from the target end time rather than counting down individual ticks. This means the timer stays accurate even if your browser throttles the tab in the background or your device briefly sleeps — you will always see the correct remaining time when you return.

Everything runs locally in your browser. No account required, no data sent to any server, and no internet connection needed after the initial page load — making it reliable even in low-connectivity environments.

Frequently Asked Questions

Does it make a sound when it finishes?

Yes, a short audio tone plays automatically using the Web Audio API when the timer reaches zero.

Can I set any time duration?

Yes. Use the custom input to enter any number of minutes and seconds up to several hours.

Does it work if I switch browser tabs?

Yes, the timer runs in the background as long as the tab remains open.

Is there a maximum time limit?

No practical limit. You can set hours, minutes, and seconds for any duration you need.

Do I need to install anything?

No. The timer runs entirely in your browser. No app installation, no signup, and no internet connection needed after the page loads.
