How to use the online alarm clock

Before handing the London head-office call to a colleague at 1:07 am, pass over the agenda, names, and any question that still needs an answer. Their evening is still under way, and the 53 minutes before 2:00 am give your colleague a clear window to review the notes without rushing the changeover.

Check where the alarm audio will actually play. A paired headset can quietly take control of the sound even when it is lying on a desk or tucked into a bag, leaving the room itself silent. Disconnect unused headphones, select the intended speaker, and run a short test from the seat where the waiting colleague will be working.

Put the dial-in details beside the device and agree who will join first if the other person is occupied. The London call could be missed if the page is closed or the device goes to sleep, since the browser cannot produce its cue then. At this hour, use a visible clock as a second reference and keep the headset ready only once someone is wearing it.

Common questions

Can I use this tool from my smartphone?

The page works on a phone, so you can check how long remains until 1:07 am while you are out. Phones often suspend inactive tabs when the screen turns off, though, and the sound may not play; for an important reminder, use a desktop or laptop connected to power.

Will it run in my phone's web browser?

You can open it on your phone and leave it counting down towards 1:07 am. The limitation comes from mobile power-saving behaviour: once the screen locks or the browser moves into the background, the alert may be silenced, so rely on a plugged-in computer when timing really matters.

Is this feature available when I am on my mobile?

It will load and run in a phone browser, including for a timer set to 1:07 am. Still, iPhone and Android devices can put background pages to sleep after the display locks, meaning the alarm is not guaranteed; a laptop or desktop left awake and plugged in is more dependable for important occasions.

Can I access it using an iPhone or Android phone?

Yes, the countdown to 1:07 am is usable on a mobile screen without installing anything. Bear in mind that phones manage battery life by freezing background browser tabs and may stop the sound after the screen locks, so an important alert is better left running on a powered laptop or desktop.
