How to use the online alarm clock

While you are laying out your running clothes and planning a waterfront route before sunrise, a 1:35 am alarm can hold the early start in your schedule. It leaves enough time to gather your keys, water and anything else you want ready before 2:00 am, rather than searching for them when you mean to leave.

A pre-dawn run depends on hearing the signal, so check that the selected alarm sound is clearly audible at your current volume. The browser alarm works only while the page remains open and the phone or laptop stays awake. If the browser page is closed, or the device falls asleep before 1:35 am, no sound will play and your waterfront run may begin late. A short sound check beforehand shows whether the alarm is reaching the speaker you expect.

Your waterfront preparations can also account for the sharp change between indoor air conditioning and Dubai’s warm night air. Keep a light layer beside your running kit if the room feels cool, but choose clothing that will not become uncomfortable once you are outside. Water placed near the door is harder to forget, and a familiar, well-lit route reduces last-minute decisions while the sun is still below the horizon.

Common questions

Can I use this tool from my smartphone?

The page works on a phone, so you can check how long remains until 1:35 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 1:35 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 1:35 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 1:35 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.
