What this tool does
Multiple labelled alarms
Add as many alarms as you need and give each one a label, so Meeting and Laundry are easy to tell apart in the list.
Live clock and snooze
The current time runs on screen so you can see how long is left, and a ringing alarm can be snoozed rather than dismissed.
Toggle each alarm on or off
Every alarm has its own switch, so a repeat alarm can be turned off for a day and turned back on later without setting it up again.
Saved locally on your device
Your alarms are stored in this browser on this device, so they are still there when you come back. Clearing your browser data clears them.
Works offline, no sign-up
Once the page has loaded it keeps running with no connection and there is no account to make. The tab does have to stay open for an alarm to sound.
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.
