Do Alarms Go Off on DND? Do Not Disturb (DND) is a useful feature on smartphones that silences notifications, calls, and alerts to minimize distractions. But what about alarms? If you rely on your phone’s alarm to wake up or remind you of important tasks, you might wonder: Do alarms go off on Do Not Disturb mode?
This guide will explain how alarms interact with DND, how to customize settings, and answer common questions to ensure you never miss an important alert.

How Do Not Disturb Mode Works
Do Not Disturb is designed to mute interruptions while allowing essential notifications to come through. When enabled:
- Calls and messages are silenced (unless from allowed contacts).
- App notifications do not make sounds or light up the screen.
- Visual alerts may still appear if configured.
However, alarms function differently because they are considered time-sensitive and user-initiated.
Do Alarms Work on Do Not Disturb?
Yes, alarms will still sound even when Do Not Disturb is turned on.
This is because alarms are treated as priority alerts. Whether you use the built-in Clock app or a third-party alarm app, most alarms will override DND settings to ensure you wake up on time or don’t miss an important reminder.
Exceptions to the Rule
- Some third-party alarm apps may require additional permissions.
- If your phone is on silent mode, alarms will still ring unless manually disabled.
- Bedtime Mode (iOS) / Sleep Mode (Android) may adjust alarm behavior.
How to Ensure Your Alarm Works with DND
If you’re concerned about your alarm not going off, follow these steps:
On iPhone (iOS)
- Open the Clock app and set your alarm.
- Go to Settings > Focus > Do Not Disturb.
- Ensure “Allow Notifications From” does not block the Clock app.
- Test your alarm while DND is active.
On Android
- Open the Clock or Alarm app and set your alarm.
- Go to Settings > Sound > Do Not Disturb.
- Check if alarms are set as an exception.
- Test the alarm with DND enabled.
What Else Does Do Not Disturb Silence?
While alarms still work, other sounds and notifications may be muted, including:
- Phone calls (unless from favorites or repeated calls)
- Text messages and app notifications
- Calendar reminders (unless marked as urgent)
- Game and social media alerts
You can customize these settings to allow certain contacts or apps to bypass DND.
Troubleshooting Alarm Issues with DND
If your alarm isn’t going off when Do Not Disturb is on, try these fixes:
1. Check Alarm Volume
- Ensure media volume is turned up (some alarms rely on this).
- Test with a different alarm tone.
2. Verify App Permissions
- For third-party alarm apps, allow “Override Do Not Disturb” in settings.
3. Disable Sleep/Bedtime Mode
- Some devices have a Sleep Mode that may silence alarms.
4. Restart Your Phone
- A simple reboot can resolve software glitches.
