Bob,
The BiaB app as well at iPad as Android is probably hardly used, mainly due to basic shortcomings. That is a pity. Many people use biab to create their music.
Many people have enough with using only chords during gigs. Many people want the ability to directly transpose the chords to the key they need. The way uploading chords and transposing has been implemented is so bad and with no reason at all that the app is completely ignored. So most people stick with iReal Pro. Just some better implementation of importing the .mgu files in the app ( doc area of iPad) or in the apps directory (Android) and a suitable direct accessable transpose function should do a lot of good for the BiaB app.
