Keep this tab open and your device awake. A browser alarm cannot ring after you close the tab or shut down your device.
Set an alarm without downloading an app, creating an account, or sending your schedule to a server. Your alarm settings stay in this browser so you can use the page for a morning routine, a meeting, or a reminder.
Open Sound settings in the header to choose a built-in ringtone, adjust volume, and test playback. Choose Silent for a visual reminder. Check that the device and browser tab are not muted before relying on an audible alarm.

The countdown compares your target with your device clock instead of adding one second at a time. When the page becomes visible again, it recalculates the remaining time. It does not need a network connection after the page loads, but the browser tab must remain open and your device must stay awake.
Set your online alarm clock in three steps:
No. Closing the tab or browser, or shutting down your device, stops the alarm; missed reminders will not ring when you reopen the page. Your alarm settings are saved in this browser, so alarms whose scheduled time has not passed will still appear in the list when you return. A one-time alarm missed while the browser was closed is removed from the upcoming list. Keep the page open and your device awake while waiting, and test the sound first. Clearing browser data or using private browsing may prevent settings from being kept.
Yes. You can set and use this online alarm clock for free without creating an account, downloading an app, or sending your alarm schedule to a server. Your settings are kept in this browser so you can return to the same device and continue using your reminders. Browser notifications are optional and the basic alarm flow works without an account.
Yes. Open the page in a mobile browser, choose a date and time, select a sound, and keep the tab open. Mobile operating systems may pause browser activity to save battery, and an alarm cannot run if the phone is powered off, asleep in a way that stops the browser, or out of battery. Test it on your device first.
Open Sound settings in the header to choose a built-in ringtone, adjust volume, and test playback. Choose Silent for a visual reminder. Check that the device and browser tab are not muted before relying on an audible alarm.
The audible level depends on your device, system volume, and sound settings. Choose a built-in tone or local audio file, then select Preview sound to hear it and make sure it is loud enough for you. Silent mode provides a visual reminder only.
The page needs an internet connection to load, but the alarm does not need to stay connected after the page and sound are loaded. It uses your device clock in the browser. Keep the tab open and the device awake while you wait; losing Wi-Fi alone does not stop the local timer, but closing the page or shutting down the device does.
Use the online alarm clock when you know the clock time you want, such as 7:00 AM or 2:30 PM. Use the online timer when you want a duration, such as 20 minutes or 1 hour. The alarm clock schedules a local time and date, while a timer counts down from the length you enter.
Browser alarms are best for everyday reminders. Keep the tab open, keep your device awake, and keep the volume on.
