How to use the online alarm clock
Waking at 5:53 pm gives you a brief moment to shake off sleep before meeting the engineer who is checking the gas boiler. The appointment may be close to 6:00 pm, so use these few minutes to get up, find any boiler paperwork and make sure the route to the appliance is clear. That leaves you ready to answer the door without rushing through the house.
With a gas engineer expected, the alarm needs to reach you rather than play quietly through headphones left connected after your rest. Check where the sound is being sent and choose a level you can hear from bed before starting it. If this page is closed or your device goes to sleep, no alarm will sound, so the boiler inspection could begin with nobody ready to answer the door. A separate household alarm provides useful backup for an appointment you cannot easily notice while asleep.
A late-afternoon boiler visit can affect everyone at home, especially if someone is working, studying or settling a child in another room. Let them know that the engineer may arrive around 6:00 pm, and keep the alarm loud enough for you but away from shared walls where possible. Leaving the hallway clear also means nobody has to move bags, shoes or coats when the doorbell goes.
Common questions
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.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
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.
