It’s not too often these days that an iPhone still surprises you. We’ve more or less seen it all by now. Except, we haven’t. #firechat is a new app that takes advantage of a little-known iOS feature that makes it easy to set up and run a network even when there’s no cellular signal.
In effect, FireChat creates a small mesh network for local users. Instead of transmitting data through a cellular signal or by connecting to the internet, the app actually creates its own mini-internet where each #mobile #device is its own node. This is also known as a mesh network, and it’s possible thanks to a new feature that arrived with iOS 7, called the Multipeer Connectivity Framework. This is great for wannabe spies, because it effectively lets you communicate off the grid.
