Frequently Asked Questions

Does the alarm work if I close the browser tab?

No, the alarm requires the browser tab to remain open. However, it will work if the tab is in the background or minimized. For best reliability, keep the tab open. For critical alarms, consider using your device's native alarm app alongside this tool.

Can I set multiple alarms at once?

Yes! You can set as many alarms as you need. Each alarm can have its own time, custom label, and on/off toggle. All alarms are displayed in a sorted list with live countdown timers showing exactly when each will ring.

Is there a snooze option?

Yes, when an alarm rings, you can click "Snooze 5 min" to delay it for 5 minutes, or "Dismiss" to cancel it. The snooze function is perfect for morning alarms or when you need a few more minutes to finish a task.

Why is there no sound when the alarm rings?

Make sure your device volume is up and that the sound is enabled by clicking the speaker icon (it should show 🔊). Some browsers require user interaction before playing audio — try clicking the "Test Sound" button to unlock audio. Also check that your browser is not muted in your system settings.

Does this alarm clock work on mobile phones?

Yes, this alarm clock works on all devices with a modern browser — desktop computers, tablets, and mobile phones. On mobile, we recommend keeping the browser tab open for the most reliable experience. Enable browser notifications for alerts even when the screen is off.

Can I use this alarm clock offline?

Once the page is loaded, the alarm clock will continue to work even if you lose your internet connection, since all processing happens client-side. However, you need an internet connection to initially load the page. Your alarms are stored in your browser's local storage.

Are my alarms saved between sessions?

Yes, all your alarms are saved in your browser's local storage. They will persist even if you close the browser, restart your computer, or return to the page days later. However, clearing your browser data will remove saved alarms.

How do I enable browser notifications?

Click the notification note at the top of the page or interact with the alarm settings. Your browser will ask for permission — click "Allow" to enable notifications. This ensures you receive alerts even if the tab is in the background or minimized.
