Pizza Compass! An app that tells you where the nearest slice can be found! No more Yelp, Google, or any other now obsolete app I have used to locate a pizza pie! I happily spent my hard-earned cash on this ($0.99) and noticed I work in a pizza desert. Home, not quite so much, thankfully.
Bestest thing about Pizza Compass? The home screen (main image) pizza slice can be dragged around to point out pizza in a specific direction and displays the name and distance. Aside from the general awesomeness, off the top of my head this is especially great for two reasons:
1. You can't afford any detours between the bar and your bed
2. You live in San Francisco and you don't want to walk up a goddamn hill for a slice of pizza
Although I have a certain respect for apps that do away with extraneous features, it might be nice to do a search by address. Say you're going to a new city and want to see where the pizza at near your hotel. But compasses don't do that. They also don't pick up data from Foursquare, so there you go. Ultimately, I would recommend Pizza Compass to my slice-loving, city-dwelling, bar-hopping pals.
