  • Great

    By Negarti1
    Always helpful, but recently I have troubles switching pages. Hope they’ll fix it.
  • It just works!

    By jdaaph
    Well what can I say? The app saved me many hassles and integration with google drive is simply the best .
  • I wish

    By Young1274
    There is some function to change only background color.
  • This is a scam

    By reikun7
    Paying $10 to download an app just to find out that you have to keep paying them more money to unlock the advertised features? This is such a scam, Apple needs to take a look at how they are advertising their product.
  • This app is amazing!!!

    By TopWarmachine
    For many years I used the Good Reader app, but since the app has been abandoned with no update in sight, I made the switch to PDF Expert. I do not regret this switch in the least. While PDF Expert does crash sometimes, the development team has put out numerous updates in an effort to increase overall stability. The ability to truly edit PDFs is an awesome feature as well, something that GoodReader never implemented. The customer service and communication with this company has been great as well. This is a great change from the lies and empty promises from the GoodReader development team in the rare event they actually will respond to any emails. From now on, I will be recommending PDF Expert to everyone I know instead of GoodReader. For those of you still on the fence about which app to purchase you will not regret getting PDF Expert.
  • Please fix the highlighting problem

    By spheniscidae21
    It’s a great app. However, sometimes the highlighter could not recognize the right text when highlighting. It was really annoying!!!
  • Recording lecture like notability pleeeeas

    By Ddgehdjx
    The app is marvelous but i wish if it has recording same as notability did it, unfortunately i wll switch to notability for this small reson
  • No Crop function

    By Doxakypie
    Manual Crop features are not available on iPAD. GoodReader has it and in spades! And get this, it’s half the price. Totally dissatisfied and wasted $10! You just bought yourselves a one-star review. Why would anyone spend $10 on this basic, I repeat, *basic* pdf reader? This is in no way a powerhouse.
  • Nice, but no cropping

    By Salll
    Allows annotations, highlighting, drawing. But doesn’t let you crop a pdf, which is a basic and important function.
  • Highlight cannot be erased

    By DrFord666
    Why can’t I use the eraser tool to erase the highlighter? I’ll change to 5 stars if this bug is fixed.
