  • Best PDF app

    By Gwen458
    Have been using for over a year, easy to navigate, edit PDFs, organize and upload almost anywhere. Can Email. I recommend Scanner Pro. Would never pay for Adobe.

  • Too bad it doesn’t work!!

    By mike z..
    The most awesome tool but doesn’t work more than 90% of the time. I wish they would fix it otherwise it’s almost useless.
  • Removed previously working features

    Used to be able to do simple text edit to PDFs but now if you want any of that be prepared to pay an additional $10 :)
  • This app is a must for business

    By Have2chooseAstupidnickname
    There's few apps that I use as regularly as PDF expert. It's let me completely digitise my office, to the point that my printer only gets turned on for those ultra rare occasions that I must send a hard copy. This is an app that I couldn't live without.
  • Crashes and Freezes

    By SneibMyuu
    This app used to be so great but now it crashes and freezes all the time. Unacceptable for accessing important documents.
  • Awesome

    By shawsome.brian
    I use PDF expert multiple times every day at work to shuffle pages around, combine PDFs, and sign them. The stability of this app merits praise. Every single other part of my workflow has broken down at one point or another, but PDF expert has never crashed on me. Even working inside of 170-200 page PDFs with complicated formatting. The ability to keep folders synced in the background is super handy, and it works great in split screen. The “Edit Text and Images” upgrade is well worth the price. I’d love it if Readdle could add a page cropping tool next. Especially one that considers Trim / Bleed / Registration and other standard printers’ marks.
