How to use the online alarm clock
As you hand over responsibility for warming the changing room before the school match, set the alarm for 6:37 am so the next person knows exactly when to take over. That leaves a clear checkpoint before 7:00 am, when players and staff may begin arriving and the room needs to be ready rather than merely starting to warm.
During the handover, check where the alarm sound will actually play. A phone may still be connected to headphones tucked inside a coat or kit bag, so the person taking over could miss the alert even while standing nearby. Disconnect them or confirm that the phone speaker is selected, then test the volume briefly. Because this browser alarm cannot sound after the browser stops running, the changing room may stay cold if the page is closed or the phone goes to sleep; keep it active until 6:37 am and use a separate alarm if that cannot be guaranteed.
With other people in the house still asleep this early, prepare quietly before the alarm is due. Keep the phone close, choose a moderate volume, and avoid leaving it on a hard bedside surface where vibration can carry through walls or floors. A nearby alert is easier for the person on duty to hear without waking everyone else.
Common questions
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.
What happens if my laptop goes to sleep before 6:37 am?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
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.
