This full-featured powerhouse makes it easy to organize, annotate and edit your PDF library. Import files from your computer or the cloud, then complete forms, add freehand drawings and audio notes and more. On an iPad, revising a PDF’s text is as simple as using a word processor, and your original content remains intact. With support for reading files from popular productivity suites, it’s a convenient way to take the office anywhere you go.

Works well for the limited number of things I do with pdfs.

Don’t do much editing. Do lots of annotating and Pdf Expert is solid with enough options to make it adaptable to most every document. I suspect if I did I might find PDF Expert app a pretty good note-taking tool. What I really enjoy is the overall reading and annotating experience. The Readdle file management is probably my favorite so far as well (meaning I like it better than Adobe Reader if your looking for comparisons). The Readdle apps seem to do a good job (better than others at least) of having options available in the “Share” menu(s). In short Readdle appears to make a good effort at utilizing the full capacity of iOS 11 as far as this neophyte can tell. Wish all PDF developers would think outside of the PDF-box more sometimes but I’m probably asking for the impossible. Ignorance is bliss I’ve heard. I suspect many problems I and other users have with Apps in general are more likely the fault of Apple’s never ending updates and tweaks which take time to find and adapt to for the Apps. Let’s face it, Apple doesn’t make it cheap to own and stay up to date with their mobile tech if you want to run various types of hardware. As such I’d tend to favor a well established company for my PDF environment. Readdle fits that description as well as or better than most PDF app developers without being a slow moving indifferent 800 pound gorilla (leave to the reader to guess who that might be in this context).

Great support service team

I was made aware of PDF Expert recently before the update to version 7, and took a while to decide to make use of it, especially the pro tools, since my needs are those of a college student.

I'm very glad I made the choice to acquire the app and its pro features however. Its the only app that actually lets to modify and work with or create pdf documents with all their features (like hyperlinks - which was my key interest for note taking). The app has a simple and hands on interface and works very well for me. My key uses for it are for organizing information ive collected from other sources and class notes, hyperlinking between my notes to improve my studies and learning, as well as, when possible with the pdfs I use, edit the pdf file itself to select elements to keep. While screenshots are wonderful and useful, and incorporating them into note apps are easy and useful, when working with pdfs, being able to use the image quality and format of the pdf books i own allows me to work with the content as is, rather than an image of it, which really appeals to me.

I had a few issues with my acquisition with regards to its update to version 7, and through this learned how attentive and thoughtful Readdle is to their user base, including new users. They made me feel like they really wanted me to make the best use of their software and feel like it should have a place in my workflow. I'm grateful to the quick responses and attention to my needs and uses.
