I did something more interesting on my iPhone with custom focus settings on iOS 15: I set up Home Screens dedicated to tasks I’m working on, and I filled it with widgets, apps and shortcuts related to my schedule; then, I set up focus categories titled with the name of that task that silences all notifications and hides all my other Home Screens. Even pauses communication with everyone except the people I allow to have access to me. Now, when I sit down to work on said task and enable its Focus mode in Control Center, or automate it turning on by location or an app opening, all I see is the Home screen with all the tools that will help execute the task at hand the most effectively.
