No internet connection or cell service? Tin Can app allows users to use WiFi signals to send messages 11/09/2013 - 00:00 Developer Mark Katakowski has created an app that facilitates a social network without an Internet connection or cell service, according to The Daily Dot. The app, called Tin Can, allows phones to relay messages between one another when in close proximity, without having to use data or SMS. Most importantly, Tin Can allows phones with the app to act as relay points for a message, even if those phones are not the intended destination.Tin Can works by connecting phones via their Wi-Fi radios, but it doesn’t require reception from any network. Messages can be sent by this connection, and they can be sent to more than one phone.
