Online Alarm Clock
Set a browser-based alarm for any time. No apps to install, no accounts to create. Enter the time you want to be alerted, and this page will play a sound and send a notification when the moment arrives. Keep this tab open and your volume up.
Why use a browser alarm
Sometimes you need a quick reminder without installing anything. Browser alarms work on any device with a web browser. They are useful for short naps, meeting reminders, cooking timers, or any situation where you want a simple alert at a specific time.
For best results, keep this tab open and make sure your device volume is turned up. Enable notifications when prompted so you receive an alert even if the tab is in the background.
FAQ
Will the alarm still ring if I switch to another tab?
Yes, as long as this tab stays open in your browser. Allow notifications when prompted and you will also get a desktop alert while the tab is in the background.
Will the alarm work if I close the browser or my laptop?
No. The alarm runs inside this page, so it needs the browser open and the device awake. For a wake-up alarm, keep your phone alarm as a backup.
Can I set an alarm for tomorrow?
Yes. If the time you enter has already passed today, the alarm is automatically set for the same time tomorrow. The countdown shows exactly how long until it rings.
Can I set more than one alarm at a time?
This page runs a single alarm. The main app lets you create several named alarms, timers, and countdowns that run side by side.
Why did no sound play?
Browsers block audio until you interact with the page. Setting the alarm counts as an interaction, so sound should work. Check that your device volume is up and the tab is not muted.
