Frequently asked questions

Will the alarm ring if I close the tab?

No. The alarm can only ring while this page is open in your browser, because it has no background access. Keep the tab open and your sound on. For something critical, use your phone's built-in alarm.

Are my alarms saved?

Yes. Alarms are saved locally in this browser and reappear when you return. Nothing is uploaded.

Can I set more than one alarm?

Yes. Add as many as you like, each with its own time and label, and toggle each one on or off.

What does snooze do?

Snooze dismisses the current alarm and automatically creates a new one for five minutes later.

Why did my alarm not make a sound?

Browsers block audio until you interact with the page. Click anywhere on the page once after loading, and keep the device volume up.
