How to Use This Alarm

Setting your wake-up call is a breeze. Just tap the big "Set Alarm" button to get started. You'll see a panel with all the options you need.

Pick a Time: The alarm defaults to the current time. You can use the dropdowns or the handy '+' and '-' buttons to quickly adjust the hour and minute.
Choose Your Sound: Select a pre-set tone, or open the "Advanced Options" to record a voice memo or have the browser speak a custom message.
Set and Relax: Once you're happy with your settings, hit "Set Alarm". A live countdown will appear, and the screen will stay awake automatically.

Frequently Asked Questions

What happens if I close this browser tab?

This alarm clock lives entirely in your browser tab. If you close it, the alarm will be cancelled. For it to work, please keep this page open.

Why doesn't the voice recorder or custom message work?

These features rely on your browser's built-in capabilities. They're supported by most modern browsers like Chrome, Firefox, and Edge. If it's not working, ensure your browser is up to date and you've given the site permission to use your microphone.

How does "Keep Screen Awake" work?

This feature uses your browser's Wake Lock API to prevent your device from going to sleep. It is enabled by default and will activate when you set an alarm. It's perfect for making sure a long-countdown alarm doesn't fail because your computer went to sleep.
