iOS 15's Focus Mode Helps You Stay on Task

Apple has long had a Do Not Disturb function that can be activated when you want to mute incoming notifications to avoid being bothered, but with iOS 15, Apple is taking Do Not Disturb to a new level with Focus.
With Focus, you set an activity that you're doing, such as working, exercising, reading, or spending time with family, and block out the notifications that are unrelated to those tasks. It's basically Do Not Disturb but with more options for refining what you see and what you don't see.
