  • Not good

    By Wendala Alistar
    I don’t like the changes! I can’t find my files!!!
  • Super Tool for Editing/Merging PDF documents

    By tunesmith
    I have owned PDF Expert for some time, but recently purchased the editor add-in so I could edit/merge PDF documents for a Medicare Appeal. The app far surpassed my expectations and did everything that I used to perform with Adobe Acrobat DC at a fraction of the cost. Great job to the developers. Highly recommended.
  • Great App - Pro Upgrade isn’t working

    By runyonski
    If you’re wondering why nobody is upgrading...it may be because the upgrade option is non responsive.
  • Holy cow, this app rules!

    By tpf1952
    I don’t usually take the time to praise an app; I just expect it to work. But PDF Expert is really a terrific app. I frequently have to share PDF documents with clients or vendors. Sometimes other IOS apps that generate PDF documents leave little or no room for making quick revisions or plugging in a signature. PDF Expert changes all that. What a time saver! This app is simply awesome. I bow my head in thanks. Get this app!
  • Uninstalled!

    By dp0123
    Apparently, it was too hard for the devs to remove that persistent black bar at the page bottom on the latest iphones. Oh well! Time to vote with my feet!
  • Poor technical support

    By CrashyAppy
    The tech support staff is horrible. They won’t even answer simple questions and rather demand that you release private information in order for them to “diagnose” a problem — rather than answering a question or simply outlining the procedure. They are lazy or retarded, and just want to check the box saying they’ve closed a ticket (if they can’t get and sell your private information).
  • Does not work with large PDFs

    By hungrycookie
    I bought this application to work with large PDFs, but it continually crashes. If that’s what you’re looking for (as a student, opening textbooks), this application is not the right one for you.
  • Problems

    By Cloudprincessruth
    In the middle of underlining or highlighting text it suddenly extends the underlining or highlighting into the next column of print. It won’t erase or right itself, so I shut the iPad off and start again. Still I have no control over where those lines go! This was badly spent money for an app. I might as well work from a hard copy because the time spent juggling the annotating is the same as if I hand wrote the material I am working on!
  • Bought months ago, can’t use

    By cactushackedus
    I paid for this app many months ago, and now it seems to be unusable unless I pay again? Not cool. I understand that maintaining an app takes time and money but that’s not how the App Store is supposed to work.
  • Best PDF app ever made
