Frequently asked questions
Does the online alarm clock work if I close the tab?
No. The alarm rings inside this page, so keep the tab open. You can switch to other tabs or windows — it will still ring.
Will it ring if my computer goes to sleep?
Usually not: a sleeping computer pauses the browser. Keep your laptop plugged in with the lid open. We ask the browser to keep the screen awake while an alarm is set.
Does it work on my phone?
Yes, in any modern mobile browser. Keep the screen on and the page open. For alarms that ring when your phone is locked, use the Alawako app.
Does it work without internet?
Yes. Once the page has loaded, the clock, sounds and alarm work offline.
Is my alarm saved if I refresh the page?
Yes. Your alarm is saved in your browser and comes back after a refresh.
Is it free?
Completely free. No sign-up, no cookies and no tracking.
Need it to ring with your phone locked?
The Alawako app for iPhone rings on the Lock Screen even in Silent mode — and makes you play a quick wake-up game before it stops.
