  • Deceptive marketing!!! Or outright LIE?!

    By Tech in Tex
    Ad/description shows text and picture editing... Highlighting and annotating is NOT editing... to actually DO editing you have to purchase an ADDITIONAL UPGRADE!? “Fool me once”.... is all you’ll get! VERY disappointed!
  • Most useful app ever

    By velgias
    Has all I need
  • Good app for readings

    By strategic fool you agent
    The reading function is good. But the compatibility of the Apple Pencil still need to be improved. Some times I can draw with hand even the pencil is linked. The function of pen and writing experience is not perfect.
  • The Most Important App.!

    By Omurcinar
    After all years of using and enjoying this fantastic app., it became the most important app that I do not thin I can function without it. If you have the full version that you can easily edit PDF documents, PDF Expert becomes a all-it-one for professional document management. So far, I couldn’t find any other app. better than this one.
  • Works great but keeps asking me to write a gd review

    By dont ask me to write a review
    Works well enough but every couple days it bugs me to write a review... otherwise 5 stars.

    Editing and marking pdf Doc is really easy and efficient. The developer should enhance the app to also be a note taking app. For what it proposes now is a great app
