Okay... not what I expected
I purchased the app to get better listening out of my new wireless headsets I purchased exclusively for workouts. The app help boost better sound quality on most songs. There are quite a few it will prohibit from enhancing stating it is blocked by Apple, which I find should have been revealed in the free trial. My main quorum is with its ability to work properly with my VWs Bluetooth connector. It malfunctions to affectively skip between songs. I wish I would have saved my money. I find it annoying to tap into two separate media players just to listen to music.
