Yes it allows fast page turning. Worst app experience ever.

Yes it pre-renders the entire PDF, allowing you to flip pages lightning fast later.

However, it forces you to sit through many minutes of confusion while the app displays very cryptic information, numbers and icons.

This is the worst user interface Ive ever seen on the iPad, particularly the choice of horrible greens and blues, non-standard methods for displaying progress during long operations, non-standard icons, and terrible layout of interface elements.

So bad that Im simply not going to use the app, even though its faster than the others.
