Set any duration and it counts down to zero with a gentle chime — in a calm, full-screen scene.

Set a countdown to any time
Type a duration on the big clock — hours, minutes and seconds — or scroll over it to dial it in, then press Start. The timer counts down to zero and rings a soft chime, so you can step away and trust it to call you back. It is the plain, reliable online timer: no phases, no accounts, no clutter — just the time you set, counting down.
Ready-made preset timers
Need a common length? Jump straight to a preset — a 5 minute timer for tea or a quick break, a 10 or 15 minute timer for a focused sprint, a 20 or 30 minute timer for study, a 1 hour timer for deep work. Each preset opens the same countdown, pre-set and ready to start, on its own page you can bookmark or share.
Calm, full-screen, distraction-free
Choose an immersive hand-painted scene or a flat color, a font and a size, then go full screen so the countdown fills the room — on a laptop, a projector or a second screen. Pop out a floating mini-window that stays on top of other apps, mute or keep the end chime, and let a depleting progress bar show at a glance how much time is left.
Share it or embed it
Copy a link that reopens the timer at the exact duration and scene you set, or drop the embed into a page, a Notion doc or a classroom slide. It is free, works in any modern browser, and needs no install.
One countdown for the classroom, kitchen and gym
The same countdown works wherever you need a visible, reliable timer. As a classroom timer, go full screen on the projector, turn on the wall-clock corner badge and let the color warnings pace an activity — readable from the back row. In the kitchen, set it for pasta or a bake and trust the loud chime. At the gym, time planks and rests. One tool, your scenarios.
Frequently asked questions
Is the countdown timer free?
Yes — completely free, no account and no install. It runs in your browser.
Does it keep time in a background tab?
Yes. The countdown is computed from a target end-time, so it stays accurate even when the tab is in the background or the device sleeps briefly.
What happens when the timer reaches zero?
It rings a gentle chime and the tab title shows "Time's up!". You can mute the chime with the speaker button if you prefer a silent finish.
Can I set a specific number of minutes?
Yes. Type any duration on the clock, or open a ready-made preset such as the 5, 10, 20 or 30 minute timer and adjust from there.
Can I embed the timer or share a link?
Yes. Use the embed page to place it in another site or doc, or copy a share link that reopens your exact duration and scene.
