How to use the online alarm clock
While preparing early for a tidal-pool hunt, you can set the 7:56 am alarm before boots, towels and a tide guide occupy your attention. It leaves a short final window to check the kit and be ready to head towards the shore at 8:00 am, without watching the clock throughout those last preparations.
A coastal morning can already be filled with running taps, a kettle, conversation or gear being moved, so choose a volume you can hear above that background noise. Test the signal from wherever the phone will actually sit rather than relying on how loud it seems in your hand. The tidal-pool hunt will receive no alert if the page has been closed or the phone has fallen asleep, so keep both active until 7:56 am and use a separate alarm when that cannot be guaranteed.
After packing for such an early outing, leave everything beside the door instead of using more of the night for repeated checks. Keeping the remaining sleep uninterrupted makes 7:56 am a clear boundary: the alarm means get up, dress and collect the prepared bag. If the trip involves others, agree the meeting details before bed so the first waking minutes are not spent exchanging messages.
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.
