10 Second Timer

One click to startAlarm at zeroKeeps time in the background

0:10

Time's up

Space to start or pause, R to reset, F for full screen.

Ten seconds is gone before you know it. Press Start and the clock runs down from 0:10, then beeps and puts "Time's up" in the tab title.

What people use a 10 second timer for

A countdown to start a race, a game or a group photo.
Quick-fire game rounds: name three animals, three states or three songs before it beeps.
Holding a balance pose or a stretch for a count of ten.
Checking the beep is loud enough before you trust a longer timer with something in the oven.

How this timer works

It remembers the moment it will end, so it stays right when you switch tabs or your phone locks.
At zero it plays a few short beeps, vibrates on phones that can, and shows "Time's up" in the tab title.
While it runs it asks the screen to stay on. Full screen makes the numbers big enough to read across a room.

Questions people ask

Why didn't the timer beep?

Browsers only let a page play sound after you click on it. Pressing Start counts, so a timer you started yourself will beep. If it stayed quiet, check that the device is not muted and the tab is still open.

How do I show a 10 second countdown to a room?

Press Full screen, or F on the keyboard, and the numbers fill the display. That works on a TV or a projector hooked up to a laptop.

Does the timer work without an internet connection?

Once the page has loaded, yes. The timer runs in your browser and does not need the network to count down or to beep.

Counting down to a date rather than a few minutes? The countdown maker works for any day, and with Pro the Countdown app puts it on your iPhone Lock Screen.
