Doesnt work on IPod touch!!!!

I was really excited to get this app, but theres an ad every 2 seconds and when I record and have it as my text tone, it does the ringtone I had before. I have an iPod touch, and it does not work on it!!!! When I try to do a song as my ringtone, nothing comes up!!!! I would really like if they made a version of this app for an IPod touch.
