The Fastest PDF Reader App Reviews

Two things I especially like: Fast rendering--this was an issue with a number of other packages when going through a paper in class. Rotation of individual pages that one can them save--again perfect for tables rotated sideways shown in class.

Using a 700 page file, the rendering is faster than any other PDF reader Ive used, and Ive tried all the top rated ones. Occasionally, there is a slight glitch, but its still light years faster than any other reader when using large files. The main issue is there is no annotation function. Anyone using PDF files which are hundreds and thousands of pages absolutely needs annotation, bookmarks, etc, to navigate through the file. Id gladly pay $$$$$ for a reader with the rendering speed of your PDF and annotation functions

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.

I LOVE the performance gains (pre-rendering is awesome) but the UI is horrible. 3 stars for performance, 0 for the UI

My favorite thing about PDF is that it displays a page at a time, rather than a continuous stream of pages. Makes it a lot easier to blow up a two column pdf and shift to the top of the next column with just a flick.

This app has changed my life! Years worth of notes, graphs, and graphics for teaching are instantly available in hi-def, professional quality. This after years of lugging around many boxes full of binders and folders! Couldnt be happier!

The help, is a joke, it only enumerates the functionalities without even explaining them or how to use them. Navigation its terrible, to go from the PDF to the settings gotta go back 6 levels of menus. No easy access to any thing. The quality of the rendering is not better than the cheapest app on the market. I just lost my money, uninstalling this ASAP.

This app charges to annotate...

One of the strangest apps I have seen. It is very no frills, dont expect to do anything but read the PDF. It does however have nested folders which is something I havent seen in a dozen other reader apps. Thats about it though unless you pay for add ons, and the interface has such oddities it feels so awkward. Once you get a PDF in the app, it spends a LLLLOOOONNNNGGG time compressing it. You can read the files before they are compressed, but not while they are compressing. Its unclear what this compression is doing since there was no obvious performance difference before and after, though while its working on any file viewing any other file compressed or not is slowed down. Once fully loaded, its hands down the fastest reader I have seen (only hit a white page that takes half a second to load one in a blue moon in a very large file that is straight image when flipping as fast as fingers can move) but getting a collection loaded could take hours while it does its compression stuff.

Works and remove lags on reading, but you have to wait for convert pdfs files.
