  • Signatures don’t work

    Update after update the signature still appears in random spots after saving them.

    I wish files would sync with document. Like if I have a file offline in documents then I’d also like it to appear in PDF expert
  • The best PDF app. The App Store.

    By malimd
    I have tried several PDF apps. This app has more versatility, accuracy, and integration than other apps. Also it is very affordable.

    Almost can’t be better. Saying this after 2 years of using it
  • Pay Per Feature - avoid

    By Nicksings
    You’d think with such great reviews that this would be an all in one app. You’d be wrong. They’ve been promising text recognition capability since 2016 (no such feature yet), and they deliberately don’t put features in the app just so you’ll have to buy other apps from them. Just look at the Developers page in the App Store... they make you buy a $5 app just to convert documents into a PDF!?! You want to print? That’s another app!!! They even make a desktop version of PDF Expert, but guess what, you’ll have to pay for that too (and it’s a LOT more money!) Money hungry company.
  • Hidden Fees Still Won’t Work

    By Xponed
    Disappointed. I spent $9.99 to buy this app, then it asked for an additional $9.99 to unlock certain features. Even after, the app will not open dynamic PDF files. Instead, it asks to have them sent to the company for conversion to static. Waste of my money.

  • Editing pdf text

    By 509down
    I really needed to edit pdf text for work and I didn’t have my computer. This app made it look like it would edit text, so i paid $10 only to find out that I had to pay another $10 to upgrade to pro, to be able to edit text. In the end it worked, but I was mislead and had to spend $20 to get there :/
