    I bought this app. And for some reason to use the same features as before I need to pay another 10 dollars. This is ridiculous.

  • Problems with last update

    By Pathfinder21
    Not sure if you are addressing the latest update, but its not working correctly with iOS 11.4. Hangs up and then crashes. Unable to use this update.
  • Phenomenal tool

    By FpgCreative
    I am a creative director, and this app gives me the ability to edit on the fly, make changes to project designs, even drawings. This is one of the best apps I’ve ever downloaded.

  • Go to productivity app

    This app saves me a lot of time. I love being able to add PDF documents from the scanner app or email directly to my iCloud account. I no longer have stacks of papers and receipts waiting on my desk to scan them into the desktop computer. The updates just keep adding more benefits and make PDF better.
  • Could be better.

    By What's the purpose?
    Would be nice if access bar had option to be on bottom, and not just sides and top.
