How to use the online alarm clock
While you are halfway through security before the Dover ferry, a 6:49 am alarm gives you a clear reason to pause, gather your belongings and check what needs doing next. It leaves eleven minutes before 7:00 am, enough time to move away from the inspection area without losing track of passports, keys or boarding papers.
Dover security may be quiet at this hour or full of announcements, rolling cases and vehicle noise, so the alarm tone needs to suit the surroundings. A softer sound can work when the phone is close at hand; a more persistent tone is safer when it is buried in a coat or bag. The volume should be checked before screening begins. This browser alarm only remains dependable while the page stays open and the phone stays awake, so a ferry security reminder could otherwise be missed.
As the queue starts moving in the early morning, changing light can make the screen harder to notice. Before reaching the checkpoint, keeping the phone somewhere visible and raising the display brightness slightly can make the 6:49 am alert easier to spot. If the terminal lighting is harsh, reducing glare by turning the screen away from overhead lamps helps without lighting up the whole area.
Common questions
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.
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.
