Good to know
Will the alarm work if I close my browser?
No. Closing the page, suspending the app, or putting the device to sleep can prevent the alarm from sounding. Use a native alarm for anything critical.
Can I use the alarm offline?
Yes, once this page and its files have been cached. Sound is generated locally. Open each tool online once before relying on offline access.
Can I use it on my phone?
Yes. Tap Enable sound after loading the page and keep the browser active. Mobile operating systems can pause background tabs or lock-screen audio.
How does snooze work?
Snooze reschedules the ringing alarm from the moment you press it. A repeating alarm resumes its normal schedule after you dismiss the snoozed alert.
Do I need an account?
No. Alarms are saved in your browser. Clearing site data removes them.
What if I return after an alarm was due?
An overdue alarm is shown when the browser resumes. It cannot retroactively sound while the device was asleep.
