Focus is a feature that helps you concentrate on a task by minimizing distractions. When you need to focus, or step away from your iPod touch, Focus can temporarily silence all notifications—or allow only specific notifications (for example, ones that match your task)—and let other people and apps know you’re busy.
You can choose from a list of provided Focus options or create your own.
Note: To quickly silence all notifications, signed in with the same Apple ID.
