HUFFINGTON POST - Apr 14 - Swoon launched last month as part of a larger initiative by Tagged to branch out into standalone apps. It launched Android to start, an iOS version is expected in May. Users connect their Facebook account -- no questionnaires to fill out, and are flipping through a bunch of Facebook profile photos with first names, ages, mutual friends and mutual interests listed. They flick a card in any direction or hit an 'X' to move to the next one. If they are interested in someone, they hit a giant green checkmark. The other party is notified of interest only if they are interested as well. Another app, Yoke, was based on the same concept, utilizing the Facebook Social Graph and Interest Graph to play matchmaker.
