Does not work at all

I bought this application to help teach my kids how to play guitar. I tested the application by having it analyze songs that I personally wrote and recorded and it was completely unable to get the chords right. I tried multiple discs that I have out and the application was never right. I tried it on discs by other artists for songs that I definitely know how to play and the chords were not detected properly for anything. It never gets the voicings right at any time.
