WiFiCast!

WiFiCast is an application that enables us to communicate in a way similar to the walkie-talkies using different devices connected to the same wifi network. To do that it uses multicast, a transmission data protocol that allows us to send data from an emitter to many receivers in a way that the network traffic is not dependent on the number of receivers. If we want to completely stop the service we will have to go to the application and push the exit button.
