Very good if you are ready to pay

This is NOT a free apps. Once you understand it and agree, the apps is quite amazing.
You will find almost everything you need in many versions (accoustic, live,...).
Great to play with a band.
Only issue: you cannot print... While you paid.
Adding videos tutorials would also be a big plus.
