Shout is a mobile app platform that allows you to easily communicate with people around with without the need for establishing friends or followers. “Shouts” appear on the feeds of all nearby users, ranked by factors including time, distance, and popularity. “Echo” shouts you like, adding value and further propagating the message. Categorize your shouts and subscribe to categories to tailor your feed. Instead of bringing your network wherever you go, Shout finds your network wherever you are.
