Online Alarm Clock

Select "Set An Alarm," choose a time, and adjust the repeat days, sound, and snooze settings. Select "Test Alarm" to preview the sound, then select "Add Alarm" to schedule it. Keep this site open on an awake device so the alarm can run.

Yes. You can save several alarms and choose which days each alarm should repeat. Every alarm can have its own time, name, sound, and snooze time, and you can turn each one on or off.

Yes. Select Edit to change an alarm, use its switch to turn it on or off, or select Delete to remove it. An alarm that is turned off stays in your list but will not ring.

No alarm can ring after you close the Just Set Alarm tab or browser. The page must remain open, and the device must stay awake with working audio.

Browsers may pause websites that are hidden in the background, especially when a device is locked or asleep. This can make the alarm late or stop it from sounding. Keep the page visible when possible, and use your device's built-in alarm or another device as a backup for anything important.

Just Set Alarm works on phones and tablets while the page stays open and the browser is allowed to run. A phone or tablet may pause the page when the screen locks, you open another app, or battery saving is on. For important alarms, use the device's built-in alarm app as a backup.

Just Set Alarm plays alarm sounds at full volume within the site. The volume you hear still depends on your device, browser, and connected speakers or headphones. The site cannot turn up those controls for you.

To make sure you hear your alarm:

• Set your device and browser volume to an audible level and make sure the device is not muted.
• Use Test Sound before relying on the alarm.
• Check whether headphones, Bluetooth speakers, or another connected device will receive the sound.

Just Set Alarm uses the date, time, and time zone set on your device. If those settings are wrong or change after you set an alarm, the displayed time and next alarm time may also change.

Dismissed one-time alarms are removed from the alarms list. Repeating alarms remain scheduled for their selected days. If snooze is enabled, selecting Snooze postpones the current alarm instead of removing it. Alarm sound stops automatically after two minutes if you do not respond.

Just Set Alarm is free to use without an account, subscription, or download. Your alarms are saved only in this browser on this device, so they do not sync to another browser or device.
