Lots of good app recommendations - let me suggest something slightly different that can help: Disable notifications. ALL notifications (barring - maybe - email and IM), including the little red counters on the icons. Move all non-essential apps off of the front page (perhaps even off of a "page" entirely). This does wonders for making using a phone a pleasant experience. The "engagement" apps no longer have automated hooks into your attention - it lets you dive into them as you want to, not as they want you to. I can go entire days forgetting that Facebook and Twitter are even a thing, since the lack of icons fools my dopamine circuits into believing that there's nothing new that requires my attention (which, mild entertainment from doomscrolling aside, is generally the truth). It makes it easy to pick a book or puzzle game instead.
