How to use the online alarm clock

Getting ready early to collect your son from training at the academy gives you a moment to check the route, find your keys and set an alarm for 3:59 pm. The signal comes just before 4:00 pm, so it can mark the point when preparations end and it is time to leave, without making the afternoon feel rushed.

Your collection reminder needs to be clearly audible where you expect to be at 3:59 pm. Set the volume above nearby conversation, television or kitchen noise, then test the sound while that background noise is present; a level that seems loud in a quiet room may disappear once the household is busy. This browser alarm needs the page running and the phone awake to sound, so relying on it alone could leave your son waiting at the academy if either stops beforehand.

Before the academy run, let anyone at home know that a brief alarm will sound near 4:00 pm, especially if someone is working, resting or on a call. Keep the phone close rather than turning the volume up across the house, and choose a short, distinct tone. That keeps the afternoon reminder noticeable to you while limiting how much it interrupts everyone else.

Common questions

Will my alarm work once I have closed the tab?

No, closing the page stops the alarm rather than leaving it active in the background. For an alert at 3:59 pm, keep that particular tab open; it can sit behind other tabs or inside a minimised browser window.

Does the tab need to stay open for the alarm?

Your device will not take over the alarm after the webpage closes. The tab containing the alarm for 3:59 pm needs to stay loaded until it rings, although you are free to switch windows, check another site, or minimise the browser.

After closing this tab, can I still hear the alarm?

If you close the tab before 3:59 pm, the alarm will not go off because its countdown ends with the page. The tab may remain out of view while you use another one, but the browser and alarm page must stay open.

Must I keep this tab open until the alarm sounds?

The alarm is tied to the current browser session, so shutting the tab or the whole browser prevents the 3:59 pm alert from sounding. Keeping the page open is enough; it can remain in a background tab while you do something else.
