Great App…LOVE IT!

I was using a very expensive PDF progam and needed to upgrade because it was not compatible with my Macbook Pro but I didn’t want to spend hundreds of dollars. I had never heard of PDF Expert and was a little hesitant to purchase. However, since purchasing this program I have been amazed at what it can do and how easy it is to use! Not only does it do...not all...but a lot of what my expensive program did…. it does it at a much lower cost.

I don’t use all the PDF Expert’s bells and whistles that the other reviewers mention, but I do scan all my household documents and receipts and important emails. Sometimes I forget to include a page(s). It’s so easy to merge the page(s) into the master document. My scanner sometimes scans blank pages or has them upside down. No worries since I can fix all those issues with PDF Expert. I love how fast I can rearrange and/or delete pages within the document. I could go on and on…but I think you get the message.

Although I purchased the app through the Apple App Store..I did have to contact the Readdle Customer Service with a minor update question. I have rarely seen such fast, professional and caring service. Alexandra at Readdle was wonderful and I also want to give her 5 stars! After reading some of the other reviews, I want to add that I have been using this prgram about 1.5 years and so far the program has never crashed nor has any of my documents been corrupted. Thank you Readdle Team!

Reliable and Smooth App

For the last 5 years I have been using iAnnotate, Acrobat Reader DC and other minor apps for PDF purposes. PDF Expert is the best by far. I am normally using PDF Expert in 2 different iPad and the mac mini2011 at the same time. I think that because of dedicated folder inside the iCloud for your pdfs, the management of those documents is very reliable between devices. Now my 3 favorites characteristics from 3 to 1. My third favorite thing is that I can open more than one screen of the app, each-one with 5 to 10+ professional books. The option to make any index in any document or just edit the current’s ones is the second best feature. The first and most awesome feature in my opinion, is the ability to open (like I said before :o) 10+ heavy professional book and make one search between all of them at the same time without any crash at all!! The app make a list of the findings so you can jump to the page in any of the book opened at that moment. Something is wrong with the app that needs improvement? not so much in my opinion… but sometime I can’t read the title of the book that I am looking at because the taps becomes small with many doc open at the same time. HINT!! Will be good a OCR capability for those pdf that shows books in picture mode. In general I recommend this App without hesitation. If you are a student, researcher or any other professional… just get it! Money well spend. Thanks!

PDF Expert rocks!

I spend bulk of my time reading PDF files, while making heavy annotations on them. In its new editions (2.X), PDF Expert has established truly praise-worthy feats in several fronts. In particular, annotating and feature-editing is now remarkably powerful and reliable. For example, you can very easily print only a certain portion of a page by simply removing other elements (figures, text, etc) to save ink. Simple dragging any image into an open PDF page, in addition to editing/cropping/re-positioning of pre-existing images, is also super helpful, if one uses PDF files as a notebook. As far as annotation is concerned, one can use an open PDF page as if it is an open canvas inside Photoshop. All these powerful functions can be done without eating up system resources.

Another pretty powerful feature is that one can open two windows from a single file—for example, the left window shows page 3 whereas the right window shows the page 7 of the same document, a truly powerful feature for side-by-side analysis of different segments of a single PDF. Personally, I would be really happy if the future edition provides a PLAYLIST function. This will allow one to create a playlist file linking to specific (eg. all the currently open) PDF files, which will then be used later to open all previously working files at once by simple double-clicking the playlist file.
