With iOS15, the Focus tool adds a revolutionary take on Do Not Disturb Mode. Focus lets you customize notifications, and sharing. The best part about Focus, is that you can set these customizations based on time, location, or while using specific apps - so you can focus.
For those who like to distinctly separate their professional and home lives, you can customize settings for either as you see fit.
If Focus is turned on you might be notified of something important, there's an option to "Notify Anyway".
Setting up Focus:
Scroll down and tap Focus.
On the main screen, you'll see: Do Not Disturb, Personal, Sleep and Work.
To begin customization, tap the + in the top right corner or any of the four sections.
Next you'll see a menu screen for different facets in your life you'd like to focus on: driving, fitness, gaming, mindfulness, reading, or a custom focus.
After selecting, you'll be able to customize when, how, and where you'd like focus turned on.
