Odd, no frills, slow then fast... – The Fastest PDF Reader Review

One of the strangest apps I have seen. It is very no frills, don't expect to do anything but read the PDF. It does however have nested folders which is something I haven't seen in a dozen other reader apps. That's 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. It's unclear what this compression is doing since there was no obvious performance difference before and after, though while it's working on any file viewing any other file compressed or not is slowed down. Once fully loaded, it's 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 it's compression stuff.
