Confused

Great choices in ringtones. Wouldve been better if there were more movies and TV shows than just music. Had a tough time locating the ringtone once I downloaded it. But cant for the life of me figure out how to attach that to my iPhone. It does not show up in my settings under sound where all my ringtones are. I thought it would be there, but it is not. I can only give it four stars. Can you make this app a little bit more user-friendly?
