Depending on your device and environment you can chat over a distance for about 20 meters or even more
without Wi-Fi / WLAN
. Also within a closed room or house or in a bunker.
Actually I never tested the chat within a bunker, but I think it could work.

Happy chatting 🙂

Technical Background

I used Xcode with completely different views for different devices 3.5 inch vs. 4.0 inch screen. This is much easier to handle then just use the same universal view for the iPhone 4, 5 and 6 etc. So I was able to connect any User Interface (UI) element with the same code behind in a Model-ViewController (M-VC) manner as Objective-C / COCOA basically supports to do so.
