You are a science denier. We ate Dominos in college because it was dirt cheap and fast, not because it had anything relating to satisfying flavor. Little Caesar's, I don't even discuss other to say it's warmed-over cardboard, which makes it roughly the equivalent to Dominos.

Not saying Papa John's, Blackjack or Pizza Hut are markedly better. But they ain't worse. (OK, Pizza Hut is worse.) 

And go with deep dish if you get Papa John's, is my advice.

Besides, who cares about apps? You pick up the phone with any of them, say "Two large combinations with triple mushrooms," and they're at your door in 20 minutes.
