How to use the online alarm clock
Uni lectures, gym sessions before work, or just a second alarm because the first one never works: 10:30 am is a popular time to want a backup. This rings from your browser at 10:30 am. No app store, no sign-up, just a tab that needs to stay open until it fires.
Pick whichever sound you're most likely to actually notice, then press Start. The alarm is tied to this browser tab, so it needs to stay open. Minimising the window is fine, but closing the tab or the browser will stop the countdown before it ever rings.
Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 10:30 am is written 10:30, and spoken aloud it's half past ten in the morning. Timetables and rosters may show it as 10:30, and handwritten notes as 10.30 am. Setting the alarm to 10:30 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
Common questions
Can I use this on my phone instead of a laptop?
Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
Can I set more than one alarm at a time?
This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
