CityTransit NYC Subway Guide

Whether you live in New York or if you're just planning a visit, you need to download CityTransit NYC Subway Guide ($2.99) to your iPhone. This must-have app , available here, makes navigating the lines far simpler. It puts the entire subway map at your fingertips, and also delivers timely info, telling you which lines are down because of weekend service interruptions, for example. We also love the GPS connection: the app uses the iPhone's GPS ability to pinpoint your location, then tell you the nearest lines to where you are. With this interactive guide in your pocket, getting around the New York City subway system is almost as easy as hailing a cab.
