HopStop So you're trying to get to your cousin's engagement party in the middle of New Jersey, but you have no idea how to get there from Manhattan. What should you do? Check out HopStop! The app will walk you through all the steps, displaying directions for a train, car or bus. It also tells me it will take 15 hours to walk there...or four hours by bicycle. Get lost? No problem. HopStop uses your current location to guide you. Turn left this time! With subway maps, bus schedules, and taxi costs, this app's a must have for any urban dweller. This free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 4.3 or later. It is also available for Android.
