Sonar (mobile application)

From Wikipedia, the free encyclopedia

Sonar was a free mobile application which showed the user how they are connected to other individuals in a room via publicly available social media profiles and location information from Foursquare, Twitter, and Facebook.[1][2]


Sonar was founded by Ocean City, Maryland, native Brett Martin,[3] and was launched in 2011 at TechCrunch Disrupt New York.[1][4] Sonar is the fourth business to come out of New York-based mobile incubator K2 Media Labs, with the previous three being Fingerprint, Tracks, and MarketSharing.[5][3]

Sonar has been offline as of September 2013, at which time Martin stated that he was no longer working on the project.[6]
