How to use the online alarm clock
Break away from what you are doing at 12:15 am so you have time to meet your relative at the National Express coach stop. The alarm marks the point when the current task needs to pause, leaving 45 minutes before 1:00 am for shoes, keys and the journey to the stop without losing track of the departure.
Your planned bus pickup depends on an alarm you can actually hear, so check whether your phone or computer is on silent before relying on it. Set the volume at a level that will cut through music or another activity, then use the on-screen indication to confirm the alarm is running. If the browser is closed or the device falls asleep, the alarm cannot sound, which could leave your relative waiting at the bus stop; a separate phone alarm provides sensible backup.
Meeting a late coach can disturb people who are already asleep, especially when doors, keys and hallway lights are involved. Put everything needed near the exit earlier, use a small light instead of lighting the whole landing, and keep the alarm close enough to silence promptly. At this point in the night, a quiet departure at 12:15 am makes the household less likely to wake while still leaving enough time for the pickup.
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.
