What is an online alarm clock?
An online alarm clock rings at a time you choose using only your web browser. There is nothing to install and no account to create. It is handy when you work at a computer and want a reminder for a meeting, a prayer time, a medicine break or the end of a study session.
You can set several alarms, give each one a label, and choose the time with hour, minute and AM or PM options. Your alarms are remembered on this device.
How the alarm works
The page compares your device clock with each alarm every second. When the time matches, it plays a tone and shows your label. Because it runs inside the page, the tab must stay open and your device must stay awake, and the sound only plays when an alarm you set goes off.
AM and PM can be confusing at 12 o'clock. 12 AM is midnight and 12 PM is noon. If you want a 7 in the evening alarm, choose 7 and PM.
When an online alarm is useful
An online alarm suits desk and study situations rather than waking up in bed. You might use it to remember a video meeting, to take a break from the screen every hour, to prepare for prayer, or to stop a long cooking task from burning. It is also helpful in classrooms and offices where a phone alarm would be disruptive, because the label on screen tells you exactly why the alarm rang. Treat it as a reminder tool and keep a phone alarm for anything you absolutely cannot miss.
How to use it
- Pick the hour, minute and AM or PM.
- Type an optional label such as Study break.
- Press Set alarm. It appears in the list and you can add more.
- When it rings, press Dismiss. Remove an alarm from the list with the cross button.
Practical tips
- Keep the tab open, volume up and the device awake.
- Set a second alarm a few minutes later as a backup for important events.
- Use clear labels so the message makes sense when it appears.
- For wake-up alarms or anything critical, also use your phone's built-in alarm.
