How to use the online alarm clock
Pulling yourself away from washing up or a half-finished programme is easier when 10:55 pm has a clear purpose: it is time to get ready for the neighbourhood patrol. The alarm separates whatever has your attention from the moment you need to collect your keys, put on a jacket and be outside for the 11:00 pm start.
A patrol reminder needs a tone that fits both the house and your tendency to dismiss quiet sounds. A softer alert may suit a shared room late in the evening, while a more insistent one is useful if you are absorbed in what you are doing. The selected volume should be audible from where you will actually be at 10:55 pm. If the browser page is closed, or the phone or laptop goes to sleep, no sound will play and the patrol handover could be missed.
Leaving an air-conditioned room during a warm spell can make the outdoor air feel unexpectedly heavy, even late in the evening. Before patrol duty, keeping a light layer and some water beside your keys avoids searching around after the alarm sounds. Turning the air conditioning down gradually beforehand can also make the move outdoors less abrupt while still leaving enough time to secure the house.
Common questions
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 10:55 pm?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
