Timer
Free online countdown timer with audible alarm. Set any duration for cooking, study, presentations and breaks. Ad-free and mobile-friendly.
What Is an Online Timer?
A timer is a countdown tool that triggers a sound and visual alert when the chosen duration ends. Unlike a stopwatch it counts down to zero. It is widely used for cooking, study breaks, kid screen-time and workout sets. The timer on this page runs in your browser, needs no install and offers preset shortcuts for 1m, 5m, 10m, 25m, 30m and 1h.
How to Use
Enter the duration in the hours / minutes / seconds fields or pick one of the preset shortcuts. "Start" begins the countdown, "Stop" pauses, "Resume" continues from where it stopped and "Reset" returns to the original duration. When time is up an audible alarm plays and a large "Done" message appears.
Common Use Cases
Cooking timers in the kitchen, brewing tea or coffee, mock-exam pacing, presentation limits, kids' screen-time tracking, HIIT/Tabata workout intervals, meditation sessions and power naps. Preset shortcuts (5m, 25m, 30m) make the most-used durations one click away.
Tips
Some systems suspend background tabs — pin the tab for critical timings. To enable sound, click anywhere on the page once after opening (browser autoplay policy). For multiple parallel timers just open new tabs.
Frequently Asked Questions
What happens when the timer ends?
An audible alarm plays and a "Done" message appears on screen. If you have granted browser notification permission you also receive a system notification.
Which preset durations are available?
1, 5, 10, 25, 30 minute and 1 hour shortcuts are one click away. You can also enter any custom duration manually.
Does the timer stop if I close the tab?
Yes — closing the tab or refreshing resets the timer. For long durations keep the tab open.
Why is the alarm not playing?
Browsers block automatic audio. Click anywhere on the page once after opening, then the alarm will play. Phone silent mode can also mute the sound.
Can I run multiple timers at once?
Yes — each browser tab runs independently, so you can open separate timers in new tabs. Useful for parallel cooking timings in the kitchen.
