WASHINGTON POST - Aug 19 - Americans now use dating apps more than online dating sites, according to a 2011 report by Flurry Analytics. Globally, the mobile dating market is expected to be worth $2.3 billion by 2016, up from $1 billion in 2011, according to Juniper Research. In June, six participants signed up for a mobile dating boot camp, organized by cyber-dating expert Julie Spira, at the iDate Mobile dating conference. They sat before a roomful of industry executives to discuss the apps they used for two weeks and provided honest feedbacks. Developers are turning to real-life concepts to woo users, like the common friend. That’s where Facebook comes in, with apps like Zoosk and Are you Interested? A new wave of apps such as Coffee Meets Bagel and Yoke focus on common friends and use Facebook profile information to match people. “You can judge a person by the company that they keep,” said Mark Brooks, analyst and consultant to the Internet dating industry. "There is no secret formula for an app to succeed", said Brooks. But “the more you can model the real world, the better you’ll do,” he said. New mobile app developers realize this and are tapping into the wealth of information available on Facebook, while trying to balance users’ privacy concerns. Spira says that just like online dating, people should apply common sense with an app.
