Foursquare
If you are the type of person who thrives on spontaneity, the Foursquare location app is the right choice for you. The interactive map pulls from information posted by friends, from your check-ins to tips that others have left about places you might like. And with the Foursquare Guide, you can get more out of your travels, whether taking in New York City culture or plotting a weekend escape to Montauk beach.
