It crashes every time I try and go back to the book menu, so all I can ever read is Gullivers Travels. Also, the interface seems unnecessarily complicated for a program that only needs to display readable text. This makes it run extremely slow on my older iPhone. Probably less annoying on newer hardware. The crashing makes it unusable for me.
