Alarm Timer
An Alarm countdown timer counts down on a full screen and rings when the time is up, which makes it a plain timer for the kitchen, the laundry or any routine you run on a clock. This page opens the timer already set to 5:00, with the sound on, so you press start and it alerts you.
A big countdown on screen and a bell when it is over, for anything you need to keep an eye on.
How to Use the Alarm Countdown Timer
Open the alarm timer
This page opens a five minute countdown with the sound already switched on. Press start and the clock begins.
Set the real length
Change the minutes or the seconds on the timer if you need another time. The alert follows whatever you set.
Leave the screen visible
A visual alarm only works if somebody can see it. Put it on a tablet in the kitchen or on a second screen.
The bell rings
When the countdown reaches zero the bell timer sounds, so you can leave the room and come back when it goes off.
Why Use This Alarm Timer
A clock you can read from across the room
The digits fill the screen, so you check the remaining time without walking to the kitchen.
The bell is already on
The beeping timer rings at zero on this page, because a timer with sound that you cannot hear from another room is not much of an alarm.
Any length, from seconds to hours
Ten seconds for the pasta, five minutes for the washing, an hour for a batch of dough. The same page handles all of them.
Free, private and offline
No account, no ads and no install. It keeps working without a connection once the page has loaded.
Where This Timer Helps
An alarm timer is the oldest interface for a deadline: you set the time and you walk away. A timer with alarm sound is easier to trust than a phone alarm, which lives in a pocket and gives you a small noise you have learned to ignore.
This alarm timer puts the countdown on the whole screen and rings a bell when the time is up. Five minutes is what it opens with, which is the usual time for an egg, a pasta or a laundry cycle, but the same timer goes from ten seconds to several hours.
Tips for making the most of it
- Turn on Auto-Repeat if the thing you are timing repeats, such as a rinse cycle.
- Name it in the subtitle, so you know from the other room whether the bell is for the pasta or the washing.
- Keep the screen on a device you can see from where you work. That is the whole point of a visual alarm.
Alarm Timer: Frequently Asked Questions
Is this a normal alarm timer?
It is a countdown timer with a sound alert, which is what an alarm timer does: you set the length, you press start and a bell rings when the time is up. The difference is that the countdown stays on the whole screen, so you can see how much is left.
How do I set a different time?
The minutes and seconds are editable on the timer itself, so you can change five minutes to any other length without touching the address. The link that gets copied keeps the length you chose.
Will it ring if the tab is in the background?
Yes. The countdown is calculated from the target moment and the alert fires when the time arrives, even if the tab is not the one you are looking at.
Other Countdown Timer Lengths
Need a different duration? Every one of these opens the same timer with the length already set.
5 minute timer
Five minutes is the most useful short interval there is. It is long enough to get something done and short enough to actually do it.
10 minute timer
Ten minutes is the sweet spot for short meetings, warm ups and focused review sessions that people actually finish.
30 minute timer
Half an hour, on screen, with nothing else to look at. It is the most useful unit of a working day.
1 minute timer
A single minute, counted down on screen as large as you need. Press start and the digits fill the screen.
