This is really overthinking it, IMO. This app isn't a shot at Yelp or an attempt to disrupt the pizza space... It's a joke. You pay a dollar, you get a pizza compass. I think it's hilarious.
The quotes on their page about "life-affirming" and "some people might say this is the most important app... ever" tell me that whoever made this app just wanted to have a bit of a laugh.
