This app has it all. For pianos amazing. I play vibraphone, keyboard based on piano, so I can easily figure out basic to extremely detailed. I did have a question & was e-mailed a very detailed response within 24 hours. So there is excellent customer support if needed. I do not own the song version, but I am sure it would be just as great. Than you

Found what I was looking for ...

Everything on one screen. No flipping between screens to change chords. Very simple, yet thorough chord coverage for me. This app has made working with sources that make use of chord symbols (real/fake books, etc.) a real breeze. Really nice to see all of the possible fingerings as well. THANKS!

Exactly what I was looking for

I wanted something that would let me work thru a lead sheet without balancing a chord book on my knee. This is it. Logical, intuitive interface and very easy to use for a beginner (me). No regrets for spending the $0.99 for this useful app. Can't find anything wrong with it, so 5 stars it is.
