    It lacks many options and is not an alternative to Acrobat Pro. You can't OCR images, nor can you generate documents from a scanner.

I wouldn't call it a "PDF Editor". It has very limited capabilities to actually edit the contents of the PDF files.

useless, overloaded, fake, all smoke and no roast!

Perhaps it has some value; however, when I used the app to re-arrange a PDF's pages, there was no obvious way to actually save what I had done. I searched through all the menus but...no luck. Maybe a decent help file or documentation would change my mind.

Agree with "perhaps." Search function is not full text, limited to overview only, rendering it nearly useless for finding anything quickly. Loaded a 922 page PDF admirably quickly, so if the search function is improved, might be worth looking at again. One star for the app, one star for potential.
