. Works as advertised . Cool integration with drop box and other online storages . Nice reading as iBooks! . PDF highlighting and notes are great too!

I can review the agreements and highlight important parts on the go. Thanks!

Excellent and very fast, even with large pdfs. It saves notes and highlights back to adobe reader pro on the desktop. 4 out of 5 because there is one kind of note in adobe pro that it does not currently support, the 'highlight and add note' notes that actually attach to the highlighted section of text. Also, there is no integration with sugarsync, which I prefer to dropbox. I hope both of these features will be available in future. Very nice though.

THIS is the Kindle killer. I've pretty literally tried all the PDF readers, trying to best exploit the great iPad advantage for booklovers: the virtues of digital reading and carrying and storage without losing a sense of real books. The iPad's PDF rendering is the answer, showing the wonderful typefaces and designs of the original books. But most PDF readers are deficient for this task. Well, finally, PDF Expert has all the features a booklover seeks, including instant page-turning. The simulated swipe of paper page-turning is phony and unsettling to the eyes. These pages change instantly to keep the reading experience going. A book is words and type and the images created in the mind. This is the perfect PDF reader to give that and vanish as the intermediary. And the easy fingertip passage-marking is brilliant. I am a totally happy reader now, thanks to Google Books, Internet Archive, and PDF Expert.

PDF Expert UI is what makes the app shine. The interface is extremely intuitive. The set of annotation tools includes only essential tools, making the application pretty simple. Along with the annotation summary, I need the ability to send the list of changes by email. This feature is presented in iAnnotate. But I need this feature in PDF Expert as I want to use only this application to work with PDF documents.

I know there is a lot of hype about auto fill forms as a feature to follow, but this app doesn't allow even manual fill of forms. You cannot type anything into this app other than post it notes. Therefore filling in a form is impossible with this app. The drawing and highlighting features work well

Downloaded this app to compare with iAnnotate, largely because so many people write positively about Readdle. While I am reasonably happy with Aji's app, I was most interested in PDF Expert for the integration with Dropbox. Unfortunately, this app continuously crashes every time I try to run it. I have tried restarting my device numerous times to no avail. The app continues to start and the immediately crash. Granted, I am running the OS 4.2 beta, so hopefully whatever bug I'm encountering gets ironed out between now and November. Until then, I can't give it a fully vetted or positive review.

Just a head up that this app doesn't work on 4.2 beta 2. It starts up then shuts down right away. I'm sure it will be a great app once it is compatible with the new firmware.

This app would be perfect if it had the same document organization options as Goodreader. My list of articles and textbooks are neatly organized in Goodreader in separate folders (uploaded as a .zip file), but in pdfexpert, there's just one long list of pdf. I hope a future update will take come design queues from goodreader. Other than that, the ability to highlight text with a stylus or finger is brilliant!

This is the most deceptive app description I've ever seen in the app store. There is an explicit claim that files can be both uploaded and downloaded from dropbox. That's not the case. There's no way to upload files back to dropbox. It's baffling that Readdle would entice dropbox users in this way with an outright lie. If it weren't for this deception I'd give it five stars.

All the cool reviews and functions are great except that they don't mention how some PDF files become blurry and checker boarded and makes it impossibly frustrating to turn pages etc. Until this problem is fixed don't buy. No point being able to take notes on something you can't see or works in a way that makes you wanna throw your iPad across the room. When I contacted them I was given elaborate instructions on how to reformat my PDF to fit their app. Hahah. One star. Not changing.

Excellent usability but the uploading process for dropbox is confusing and cumbersome. And will crash with larger PDFs.

Truth be told, PDF Expert is perfect for people who do work with PDF files on a daily basis. As for me, I use it daily for my lecture slides: I can make notes, highlight, underline and cross out. Thanks for adding the ability to organize files, now it's even better. Absolutely recommended for people who work with PDF files.

Nice, unobtrusive interface. Seems to handle large/complex PDFs well. Easy to get documents in. Easy to make annotations. It's less good at seeing what annotations you've made. The list shows that you've made a highlight, but not the text you've highlighted, so it's hard to find a particular annotation. I'd like to be able to treat my highlights as an outline and use them to navigate the complete PDF, but the annotation list doesn't currently allow that.

No question this is the best app for PDF viewing and markup!

A great app for sure. The Readdle connection is fantastic. Tech support is superb answering my annoying questions. Highly recommend.

I like most everything about PDF Export so far, with the exception of it's extremely poor bookmarking capabilities and functionality. Why they didn't create it to function the same way they did in ReaddleDocs is beyond my understanding. The first function that is missing is the ability to add a new bookmark on the fly using the selected text. They had a similar function in ReaddleDocs until the last update and they removed it. Why? I don't know, but It really gripes me! Currently to create a bookmark containing text from the document itself, you first must select and copy the text you want to use. Then click on the + icon to add a bookmark, then you have to click on the x to remove the page number text that is used as the default bookmark name, then you have to tap and hold, and finally paste the text from memory (clipboard) to use as your bookmark. Oh and don't forget to click the "Done" icon or all that work is for nothing. What a hassle! Instead they need to include the ability to add a new bookmark on the fly. Currently when selecting text, the popup menu contains the following commands: Highlight, Underline, Strikeout, Note, and Copy. Well they need to add one more command labeled "Add Bookmark" and then let you edit that text if desired before saving the new bookmark. I sure hope they add this option to the next update, it would be a huge time saver! It's evident they rushed PDF export out the door before the bookmark functions even worked properly. When adding bookmarks, they don't maintain their chronological order! Maybe it's just a bug and they'll fix it soon, but I mean come on, how much testing would it of took to realize that doesn't work properly before they put the app on the market. I haven't yet figured out what order the bookmarks are being saved in, but it's not much good the way it is. Additionally, the only bookmark editing capability PDF Expert has is the ability to DELETE a bookmark! What the heck? Why do they even bother using the word edit? There is no editing function! They got it right with ReaddleDocs but totally missed the boat with PDF export. ReaddleDocs provides the ability to edit the text and reposition the order of bookmarks in the table of content. These functions need to be added to PDF Expert too. Once that's accomplished, I'll be able to give it 4 stars. At least the annotations I've made to my PDF files while using ReaddleDocs carry over to PDF Expert to include any notes I've added. However, bookmarks made in ReaddleDocs do NOT carry over to PDF Expert, so that's a real shame. I've spent a lot of time in ReaddleDocs bookmarking my PDF files to create a nice table of contents but will now have to re-create those bookmarks in PDF Expert. The same basic file editing functions are available in PDF Expert as are available in ReaddleDocs. They include: Copy, move, delete, mail, Zip. The settings currently available are also all pretty much the same as ReaddleDocs: Passkey Lock, Wi-Fi Drive, Viewers - Highlight links toggle switch, Auto Open on Startup or File Download, Support and a Legal Notes information file. It appears to have the same "Add Server" ability as ReaddleDocs. Also with PDF Expert (as with ReaddleDocs) you have the ability to Lock Page Scroll (I haven't figured this one out yet?) Send by E-mail, Text Reflow, and Open in other apps. You don't have the ability in PDF Expert that you do in ReaddleDocs to add Mail Servers such as GMail, Hotmail, MobileMe, AOL Mail, Yahoo Mail Plus and other E-Mail Service using POP3 or IMAP type accounts. So I suppose that's the big difference in ReaddleDocs and PDF Expert and since PDF Expert is mainly designed to read only PDF's while ReaddleDocs is designed to read so much more. I haven't noticed any problems with blurry files or slow page turning as one reviewer mentioned. Also another reviewer may have been wrong about the apps ability to upload/download files unless he was having a specific problem with Dropbox (I don't use Dropbox) however PDF Export DOES in-fact have the ability to upload and download files to an iDisk without an issue, I would assume it works the same way with Dropbox. I too at first didn't see how to accomplish this task, and thought the application description in iTunes was deceiving. However, I finally discovered how to do it after playing around with the app a bit further. It's also well documented in the user guide. Some other suggestions if implemented, would allow me to give PDF Expert 5 stars. 1. They need to enable the highlighter with the ability to remember which color was used last. I was told they have plans to add this feature, so I'll keep my fingers crossed. 2. The ability to use more than one method of annotation on the same selected text. For example, I would like to be able to highlight and underline selected text at the same time. Apple Preview allows you to do that with a PDF document on the Mac, perhaps you can't do that on the iPad I'm not sure, but it would be nice! 3. They also need to implement the magnifying glass revealing the line of text you are selecting. That would make it much easier to select text. I'll have to admit at first I was reluctant to convert from ReaddleDocs to PDF Expert, primarily because of the problems involving the bookmarking functionality. But I suspect they will soon rectify these problems (as least I hope so!). After experimenting a little further with PDF Expert, I've decided to make it my PDF reader of choice and understand that I will still have a need for ReaddleDocs, its just too bad they can't merge the two apps into one "Do All" app, that would be the bomb!

This has become my favorite PDF app. Annotation capabilities are great. I was using a competing app and switched to PDF Expert. Simpler two-way syncing with dropbox would be a great addition.

Read other reviews before buying this, and it has lived up to it's rating. This tool has allowed me to add annotations to student papers as I'm grading, using my iPad. I can save pdf files to Dropbox and open them for annotating in PDF Expert, then copy the graded files back to my computer using ITunes. Unfortunately comments are lost when emailing directly from the app, so found it best to upload batches of files at a time. Very nice, simple annotation interface, and the comments save with document so students can easily read my notes inline. Using a BoxWave stylus makes handwritten notes easier, but the only thing I would like is smoother/finer writing and drawing, similar to the feel of Penultimate.

I like this app better than Readle Docs, because it allows for both highlighting and underlining of PDF docs. So far, I've had no problems, and I'd strongly recommend it to anyone who has to deal with PDFs on an iPad.
