The idea behind Wifi Password Hacker PRANK is to make your friend believe that you have an app that can hack her WiFi network. The only thing the app will do is show a black screen with green Matrix-style letters, which obviously won't do anything at all.
Wifi Password Hacker PRANK is just what it sounds like: a joke app that may be useful for some people. This is one of those apps that are perfect to use on your in-laws.
Requires Android 2.3 or higher
