Although the indexes take a little time to adjust, this is the best app ( I tried a least a dozen) for reading and playing from your digital fake and real books.
it is the only app that can subtract playlist including the PDFs from the songs on the playlist and then can be send by email.
Now it also supports landscape mode.
Do understand you have to find your own content, real book pdfs etc.
A Must Have for musicians who really care. Much better then the superficial chords only stuff from the iRealbook Pro app. Music is about melodies remember, not just about chords:)
The flaws: a strange temporary freeze in the view mode of the books, still a not so intuitive way to adjust the indexes, still missing some essentials book indexes, the whole interface looks far from slick, a little make over for the over all look and feel would be appreciated, an option for making your own indexes would be a great addition.
But despite all this: great app!
