Disclosing authorship of controversial app in CV
I don't think having created an app that was, it seems, more a proof of concept will impact your acceptance or failure to be accepted much. For completeness and honesty, one might think it does belong on a CV though. However, the way you describe your app I would add a clarifying brief description, such as "Parody of political process." You wouldn't want more people getting the wrong impression your professor originally had, without being in the room and able to explain yourself. 

It seems that you are middle-of-the-road politically, bemused and maybe annoyed by orthodoxies left and right of you. Keep in mind that your app, if this is expressed in it, will probably make both the left and right uncomfortable and head-shakingly displeased: for card-carrying members of the (far?) left and right, anyone not with them, is against them. So be careful.
