“Dovetail is a free smartphone app that transmits text messages to and from people physically near you, using only your phone’s built in wi-fi transmitter to communicate. Dovetail is not designed to send messages to a specific person. Instead, a message sent via Dovetail is “broadcast” to all other nearby users to create instant “group messaging,” akin to a mass tweet or old-school IRC chat. In other words, Dovetail enables one-click, group “chats” with all the people around you.”
