METRO.CO.UK - Feb 13 - A game-changing gay dating app that launched last year and is now available in London, New York City and LA, Chappy has a lot in common with Bumble so much so that Bumble's founder Whitney Wolfe is one of its backers. Chappy gives users a choice between relationships or hook ups. They've put rules in place so that users' face has to be on every picture, and keywords get flagged whether it be drugs or violence. "Immediately on Grindr and other apps you can send a pic of your dick immediately without speaking – that's not happening on Chappy. First you have to make a match. To be clear we are not against dick pics – we are against unsolicited dic picks," said Locke.
