Our online alarm clock uses your device's local time and plays a sound through your browser when the set time is reached. Simply choose your alarm time, pick a ringtone, and click "Set Alarm." Keep the browser tab open for the alarm to trigger. You can use the snooze function to delay the alarm by 9 minutes.

No. The alarm requires your browser tab to remain open and your device to stay awake. If your computer enters sleep mode or the browser tab is closed, the alarm will not sound. We recommend keeping your device awake and the tab active for reliable alarm functionality.

Modern browsers may require a user interaction (like clicking a button) before playing audio. When you click "Set Alarm" or "Test Sound," this grants the necessary audio permission. If the alarm fails to produce sound, try interacting with the page first.

Absolutely! This alarm clock is fully responsive and works on all modern smartphones and tablets. For best results, keep the browser tab open and your phone's screen on. You can also add this page to your home screen for quick access.

We offer four distinct ringtone styles: Classic (traditional alarm beep), Digital (fast electronic pulse), Melodic (gentle alternating tones), and Buzzer (urgent sweeping frequency). You can preview each sound using the "Test Sound" button before setting your alarm.

When the alarm rings, clicking "Snooze" will silence it for exactly 9 minutes — the classic snooze duration. After 9 minutes, the alarm will sound again. You can snooze multiple times. Click "STOP" to fully deactivate the alarm.

Yes! Everything runs locally in your browser. We do not collect, store, or transmit any personal data. The alarm time, sound preferences, and all settings remain on your device. No account or registration is required.
