FireChat is an iOS chat app by developer Open Garden that uses the Multipeer Connectivity Framework built into Apple’s iOS 7 software to circumvent the need of Internet or mobile phone coverage when sending images or text. Essentially, the app makes use of this peer-to-peer Wi-Fi and Bluetooth capability to connect devices together without the need for a connection of that kind. The app works best in this “Nearby Chat” mode when within 30 feet of other users, and is currently available in Apple’s App Store.
