  • Great!

    By ALDiCross
    Better than a desktop version which will start at 70$-140$, this has all of the same powerful features and you can use the app on multiple devices for 20$! This is the best deal: can use on other apps like documents also, with the best features, at the best price anywhere, whether it’s desktop, tablet or phone.
  • Ask you for more money

    By TeX King
    I bought this app long time ago. The developer should keep this app working well. Instead, the developer makes this one to have glitches so that it keeps asking you to upgrade to a Pro version, which requires you to add another $10. I will stay entirely away from this kind of developer.
  • Best PDF Reader Ever!

    By DesertRat47
    I read a lot of long PDF’s and most readers are weak for such reading. They all seem to have something I don’t like or wanting something I would like to have.... This reader has it all, stop looking, just buy it!

    Best pdf reader. Way better than Adobe pdf reader
  • 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!
  • Great app overall

    By Hell0drs0ul
    Nice app. Better than the Acrobat at handling large files. Just a few suggestions. May we please get the option to hide “Recently deleted” folder from the home screen of the app? Also if we get the option to specify the number of folders displayed in one row of the grid view of the app, it will be nice I think. Currently the app has no option and by default it displays 4 folders/files in one row of the grid view. This makes it difficult to see the whole name of the folder/files if it has a lengthy name. Best of luck. Great work!
  • Has AirPrint Defect

    By SwankPeRFection
    When printing a modified PDF (one or more pages) to an OfficeJet Pro 8710, one of the pages comes out extremely blurry on the printout. This only happens with this app.
  • Ios version is good but Mac version is buggy

    By heavy note user
    When editing the text box the mouse got very slow, can barely move when the index is on the text box.
