THE WASHINGTON POST - Sep 12 - Americans now use dating apps more than online dating sites, according to Flurry Analytics. In June, Julie Spira, an author and cyber-dating expert, organized a first-of-its-kind mobile dating boot camp during the iDate mobile dating conference. Six participants tried two online dating apps for two weeks and provided honest feedback to the online dating industry executives. The perception about mobile apps, which is not totally inaccurate, is that they're meant for casual dating. 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.
