Foursquare is a location-based social networking website, software for mobile devices, and game. Users "Check-in" at venues using text messaging or a device specific application. They are then awarded points and sometimes "badges." The service was created by Dennis Crowley and Naveen Selvadurai; Crowley had previously founded the similar project Dodgeball which Google bought and shelved in 2009.
Foursquare allows registered users to connect with friends and update their location. Points are awarded on weekends and non-business hours for "checking in" at venues. Users can choose to have their Twitter accounts updated when they check in. In version 1.3 of their iPhone application, Foursquare enabled push-notification of friend updates, which they call "Pings." Users can earn badges by checking in at locations with certain tags or for check-in frequency. The company has stated that users will be able to add their own custom badges to the site in the future. If a user has checked-in to a venue more than anyone else, on separate days, and they have a profile photo, they will be crowned "Mayor" of that venue, until someone else earns the title. Users can create a "To Do" list for their private use and add "Tips" to venues that other users can read.
Foursquare is currently available in 100 metro areas, including Amsterdam, Atlanta, Austin, Boston, Chicago, Dallas / Fort Worth, Denver, Detroit, Helsinki, Houston, Las Vegas, London, Los Angeles, Miami, Minneapolis / St. Paul, New York City, Pittsburgh, Philadelphia, Phoenix, Portland, San Diego, San Francisco, Seattle, Toronto, Washington, D.C.
Foursquare currently has an iPhone and Android application and is working on applications for BlackBerry and the Palm Pre.
