Gun Identification App
So I am about to get my first smartphone and someone told me that there was a gun ID app out there. As described to me its basically just like it sounds, an image of a firearm is displayed and you are asked to identify it through multiple choice. For example a M1928 Thompson will be displayed and options like M1A1 and M1921 will be options along with something obviously wrong like Steyer TMP.
Anyway, anyone know anything more about this? Or was I given incorrect information...
