Online Alarm Clock

Set a simple online alarm in your browser

This online alarm clock rings at the time you choose and works right in a browser tab. Set as many alarms as you need, and each one will run independently in your browser. It's handy if you need an alarm on your laptop when your phone's charging elsewhere, or a reminder to end an online meeting.

Get started

1. Tap "Set Alarm" and pick a time, or choose one of the presets for common wake-up times. The preview tells you when the alarm will fire, for example "Tomorrow 7:30 AM, 8h 12m". Make sure your device will be awake when the alarm fires.
2. Click the icon in the top right or hit F on your keyboard to enter full-screen display, and click Show clock / Show countdown to toggle between clock and countdown views.
3. Hit Dismiss or Delay when the alarm goes off.
4. Use the settings to change the time format and alarm volume.

Note: Always check your sound and device sleep and power settings before setting a critical alarm, since the alarm won't ring if your device is asleep or off.

Set alarms across devices

Your list of preset alarms saves in the browser, but when you refresh the page or return to it from another device, you'll need to click somewhere on the page for the alarm to sound. If your list doesn't show on the page, check that your browser allows site data and storage. Use the Login option (bottom left) to sign in or sign up and access your list across devices.

FAQs

Will the alarm ring if I switch to another tab?

Can I set more than one alarm?

Yes, just add as many as you need. Each alarm runs on its own schedule.

What time zone does the alarm use?

The alarm time is set in your device's local time and will follow your device across time zones.
