This is a very bad app. I use the website sometimes, but for a particular song (smooth santana) i wasn't sure of where the riffs fit in the rhythm, so i wanted to know how it sounds. I got the app so i could listen to it, and every version of the song i tried to listen to, it wouldnt let me listen to it because i needed the 'pro version'. Seriously, it was just one song. Come on Ultimate Guitar, now I have to find another tab. Wouldnt have had to do that if it just said "pay to hear this song"
