Bumble connects you to people around you. After two people mutually opt in by swiping right, they're added to each other's 'hive' of connections. The woman has to say something first within 24 hours or the connection disappears forever.
citysocializer is the local, social life app to do more of the things you like with people going out around you. A place that combines having fun with new people offline, and a place to stay in touch with them online as your new network grows.
