Excellent

I really like the direction the developer has taken with this app. It has useful, sensible features and not a lot of fluff. Its very well thought out. Using the intertial sensor to function as a page-turner is brilliant. Its got a few glitches, but nothing that has gotten in the way of the enjoyable use of PG SongBook. The developer provides super-responsive customer service, so it looks only to get better. Even with the glitches, I give it full marks now.
