Use Do Not Disturb on your iPhone, iPad, and iPod touch

When Do Not Disturb is on, you see a crescent moon  in the status bar. There are two ways to turn Do Not Disturb on or off:

If you set an alarm in the Clock app, the alarm goes off even when Do Not Disturb is on. Learn how to set and manage your alarms.

If you don't want to be disturbed at a certain time, you can set a schedule. Tap Settings > Do Not Disturb and turn on Scheduled. Then set a time.

You can also choose when you want to receive alerts, calls, and notifications:

• Bedtime: When Bedtime is enabled, the Lock screen will dim, calls will be silenced, and notifications will appear under During Bedtime in the Notification Center until your scheduled Do Not Disturb ends.
• Silence: Choose to silence calls and notifications always or only when the device is locked.
• Allow Calls From: Allow calls from everyone, no one, your favorites, or specific contact groups stored on your device or iCloud.
• Repeated Calls: If someone calls you twice within three minutes, the second call isn't silenced.

• Use Do Not Disturb While Driving to silence notifications automatically when you're in your car. 
• View and manage your notifications and reduce interruptions throughout the day.
