Foursquare is a location-based social networking game that lets users “check-in” at venues and meet up with friends nearby (Foursquare for iPhone is shown in Figure 4-1). The app handily combines everything from Core Location to push notifications, and its ambitions run deep. It aspires to be a multipurpose tool for socializing, complete with Yelp reviews, maps, nearby tweets, and user profiles. Despite its breadth, Foursquare maintains an economically-designed interface that makes the iPhone’s screen feel bigger than it is.
