Gentle wake-up
The volume can rise gradually over up to 60 seconds, so waking up feels softer.

Frequently asked questions
Does the alarm work if the tab is in the background?
Yes. The tab can be in the background and the browser window behind other windows — just don’t close the tab or the browser. When possible, the app also keeps the screen awake.
Is my MP3 file uploaded anywhere?
No. The browser reads the file straight from your computer — it never leaves your device.
Is the alarm clock free?
Yes, completely free — no account, no ads, no limits.
Does it work without an internet connection?
Once the page has been opened, the alarm works offline too, because the whole app runs in your browser.
What happens if my computer goes to sleep?
A sleeping computer may not play the alarm. Make sure your computer doesn’t sleep automatically, or leave the screen on — the app tries to keep it awake by itself.
How does snooze work?
When the alarm rings, press “Snooze” — the sound stops and rings again after 5, 9, 10 or 15 minutes, depending on your setting.
