FAST COMPANY - July 5 - Happn is launching locally in San Francisco. The app is already live in New York City and a few other U.S. markets. In total, the app boasts 2.5M users worldwide. Like Tinder, Happn's functionality relies on users' location, but instead of surveying the surrounding neighborhood or city, it zooms in much more closely, to a 275-yard radius. The app's purpose is to help users "find the people they've crossed paths with." Happn offers users a form of digital flirtation called "charms." If users haven't matched up yet, they can send somebody a charm to get their attention. Every user gets 10 free charms. Once those are used up, they can purchase 10 more for $1.99.
