How to use the online alarm clock
As you finish what you are doing and leave for your GP appointment, an alarm at 11:20 am can mark the moment to set off rather than the time to start getting ready. It leaves a clear boundary between your current task and the journey to the surgery, with 12:00 pm still ahead. Keep your coat, keys and any appointment details together so the alert leads straight to the door.
Your departure depends on the alarm sounding after the phone or computer has been left alone for a while. Set the volume to an audible level, then keep this page running and the screen awake until 11:20 am. If the page is closed or the phone or computer falls asleep beforehand, the browser alarm may remain silent and leave you late for the appointment. A separate alarm on the device is a sensible backup when you expect to put it in a pocket or bag.
Reaching a surgery late in the morning can take longer than the quietest estimate, especially near busy high streets, school traffic or roadworks. Check the route before settling into another task and allow time for parking, a bus delay, or the walk from the stop. At 11:20 am, leaving promptly also gives you some breathing room to find reception without rushing.
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.
