  • It’s the little things

    By Olao999
    I feel like I really need add this so my review: The little details add up to a delightful experience. I recently noticed that you can work with documents on the cloud directly, or that if you jump to a bookmark you get a “go back” button, or that highlighting intelligently detects whether you meant to use your finger or pencil. It’s a very well thought user experience. Original review: This is the best PDF reader in the App Store period. It renders the actual PDF faster than any other app, it supports multiple PDFs open at the same time, highlighting works great, it has everything! I take a lot of notes and read a lot or textbooks and papers. While reading, i make quick notes and highlight in PDF Expert all the time. I prefer this to import my PDFs in any other PDF app because PDF Expert is so much faster and fluid all the time.
  • HORRIBLE!!!!

    By ohwoeufhWefueigpwef
    Was forwarded to this app when I tried to edit text in Scanner pro only to find out in addition to the 9.99 I already paid I now must download another app and pay an additional 9.99 all to change 1 number on a pdf!!
  • No complaints here!

    By Jonbad2u
    Using this app is now second nature to me. It’s not only useful for work but handy in every day life as well.
  • Excellent! (Also)

    By PhilTrit
    The review that I was drafting suddenly disappeared! Then I see that others have gone into far more specific detail then was high. Suffice to say this is the best PDF app I’ve found and I’ve tried a bunch of ‘em. It is simple to use and has a very clean appearance. It has more features than I’ve been able to explore, but the text change I made to a training handout was brain-dead simple to do and the correction was indistinguishable from the original font. This app is a keeper!
  • Almost on par with the Mac app

    By thevanillaspy
    Pros: - Nice interface and well implemented cloud-integration (Google Drive, Dropbox, iCloud...) - Using both the Mac app and the iOS app makes it easy to be productive on the go and at work Cons: - iPad screen-space is under-utilized -- basically the Mac version has figured out how to use large screens really well, and the iOS version has none of that engineering. (The Mac version of PDF Expert has a split-view, which would do really well on the iPad, for side-by-side document work. Also, there is no two-page view, which is available on the Mac version.) - External keyboards are supported, but are under-utilized (there's no keyboard shortcuts).
  • Where is Redo button?

    How to cancel Undo during Annotation?
  • Scam

    By DatNI99A
    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.
  • Nice except crashes iPad a lot...

    By Spbelly
    ...fortunately it does save everything done up to crash.
  • 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.
