To turn off notifications on an iPhone, there are a few key ways:
- Use Do Not Disturb (or Focus mode):
- Swipe down from the top right to open Control Center.
 - Tap Focus, then tap Do Not Disturb to silence all notifications temporarily.
 - This mode can be toggled on or off as needed for quick silence of notifications.
 
 - Turn off notifications for specific apps:
- Open the Settings app.
 - Tap Notifications.
 - Scroll to find the app you want to silence.
 - Tap the app and toggle off "Allow Notifications" to stop all notifications from that app permanently.
 
 - Manage notification previews and styles:
- In Settings > Notifications, you can change how notifications appear on the Lock Screen or if previews should be shown.
 - You can also schedule a summary of notifications or silence them for specified periods.
 
 
These methods allow selectively turning off all notifications temporarily or permanently per app to customize notification preferences on an iPhone.
