How does it function?The app browses for other users nearby while simultaneously broadcasting to peers that it is available to connect to. According to the company, this "Nearby" mode works best when the devices are within 30-feet.
This allows you to be invited into a "session" with multiple users. Each user has to be within range of just one member of the chat, so the mesh can spread outwards and cover a lot more range as more people join in.
Once a session invitation is accepted, you can directly communicate with those other users independent of a cellular signal or Wi-Fi access.
This creates what is called "wireless mesh network".
According to Benoliel, "Messages also get deleted as soon as you close the app so you remain anonymous."
However, in "Nearby" mode, you do not have any choice over who receives your messages they go out to anyone within range, the report added. There is also an "Everyone" mode, which sends the messages over a data connection so you can chat with friends who are not physically nearby. This is being segmented into chatrooms of 80 users each as the initial rush of downloads made it untenable to keep all users on a single chat.
Apple sold 700 million iOS devices by last October. Many are already using the latest Multipeer Connectivity-supporting version of iOS.
Within a week of its launch, FireChat has been being downloaded from the App Store more than 100,000 times a day.
