How to use the online alarm clock
You are packing away what you were doing at 7:29 pm and heading out for your darts team’s training session. An alarm at this time gives you a clear cue to collect your keys, darts case and water, then leave without repeatedly checking the clock. With 8:00 pm approaching, there is still time for the journey and a calm arrival rather than rushing through the door.
Your departure depends on hearing the alert, so set the volume high enough to carry across the room and choose a sound you will recognise over evening noise. Check that the alarm is visibly running before putting the phone down. A browser alarm cannot wake a sleeping phone or work after its page has been closed, which could make you late for darts training; keep the page active and prevent the phone from sleeping until it rings.
As you finish up under evening lighting, avoid staring at a bright screen while waiting for 7:29 pm. Lower the display brightness to suit the room, use the warmer colour setting if available, and place the phone where the alarm remains audible without keeping it directly in view. That leaves your eyes on packing your darts gear and checking you have everything, while the alert handles the timing.
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 7:29 pm?
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.
