How to use the online alarm clock
Watching the clock beside the tills makes 3:06 am the point when the final stretch of your supermarket shift becomes manageable. An alarm set for that exact time can mark the moment to finish the remaining checks, hand over any notes and prepare to leave, while 4:00 am remains nearly an hour away.
During a quiet spell, the alarm page may sit behind the rota, a message or another browser page. Background pages can receive less attention from the browser, particularly when battery-saving settings are active, so keeping this page available and the sound turned up gives the alert a clearer chance to play. A fully closed browser or sleeping phone could leave the supermarket shift without its 3:06 am signal, so a separate alarm is sensible when missing the time would hold up the handover.
Near the end of a night shift, bright ceiling lights can make the area outside seem much darker than expected. Before clocking off, it helps to lower the screen brightness gradually and have a coat, keys and travel card ready under the shop lighting. A small torch or the phone’s torch can also be positioned for the walk across an unlit staff car park without searching through a bag after leaving the supermarket.
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.
