How to use the online alarm clock
If the afternoon has you juggling pickups, training runs, or a second job starting later, 4:10 pm is worth setting properly rather than trusting memory. This tool rings at 4:10 pm straight from your browser, loud enough to notice over the usual afternoon noise at home.
Using it is simple: pick a ringtone from the list, press Start, and leave this tab open in your browser. The alarm runs entirely on this page, so closing the browser will stop it from going off. Come back a minute early if you're not sure you trust it yet.
It's free to use, doesn't need an account, and works the same in any modern browser, but it's honestly not meant to replace your phone for anything you can't afford to sleep through. Keep the tab open and the device awake, and it'll ring reliably at the time you set. On a 24-hour clock 4:10 pm is written 16:10, and spoken aloud it's ten past four in the afternoon. Timetables and rosters may show it as 16:10, and handwritten notes as 4.10 pm. Whether you would say set alarm for 4:10 pm or put an alarm on for 4:10 pm, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
