> reduces distractions
Have you looked over the shoulder of somebody trying to "do" something on their phone recently?
If so you might have noticed the constant pings and notifications from dating apps, news sites, random games and cool-apps-that-you've-long-forgotten-but-still-have-location-and-background-services-turned-on.
I mean, some, sure. but it's a choice, and not all choose to do that. and I've watched quite a few (of all ages) escape it when they realize how much it's harming their ability to do what they need to do.
That's where Reduce Interruptions on the iPhone (or Do Not Disturb) comes in handy.
