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.

Indispensable App & Superior Customer Service!

For over 6 years I’ve been using this app & it has been a fantastic experience. There was a learning curve in the beginning but after that I’ve had nothing but positive experiences. Originally I bought PDF Expert to study & archive periodicals but it has become an integral part of my iPad life: keeping all of my scanned bits of paper & recipes organized, filling out online forms, even doing creative projects. And talk about customer service! If only all companies had their finesse! I’ve had to contact them 3 or 4 times with questions & not only do they write back promptly but the tone of the response is thoughtful & friendly. And I don’t know if it was just a coincidence but early on there was only a deep purple highlighter so dark to be almost unusable so I submitted a request for lilac. On the next update lilac was there! Now, of course, there are plenty of color options. Another time I wrote them because I couldn’t figure out how to do something & they wrote me back as if they had nothing better to do than help me. So impressed. With every update PDF Expert only gets better. Bravo to the Readdle team! Congratulations on many excellent products backed by a superior customer experience! Keep up the good work!
