  • Five stars doesn’t do it justice...

    For 10 bucks, this app is a steal. I’d gladly pay $100...a month...for this genius piece of software. For far too long I lived with the delusion that a certain clumsy, user-unfriendly built-in app was the best way to manage my PDFs, under the demonstrably false impression that since they built the operating system, they would know how to best take advantage of it How very wrong I was! On a whim I decided to give PDF Expert a chance, and I have never looked back. Never mind that I had to basically delete my entire unruly collection of thousands of unorganized PDFs and start anew (coz exporting from said app can be difficult and fraught with restrictions). But I have zero regrets. It was totally worth it. PDF Expert is the best app for any iOS device hands-down. I can’t even tell you how many times I’ve thought to myself “Gee, it would be great if PDF Expert could do X,” only to find out that not only can PDF Expert do X, but doing X is so simple and intuitive. Between this app and Documents (which is my second favorite iOS app), the geniuses at Readdle should be writing the book on iOS app development. In fact, Apple should just throw out their entire in-house app development staff and farm everything out to Readdle. Imagine how powerful iOS devices would be... I wracked my brain for hours to come up with something—anything!— that I could suggest for future updates, but my mind came up blank. PDF Expert is truly the perfect app. I guess the only thing I could suggest is keep making more and more of these fantastic apps.

  • Great product

    Use it all the time
  • Too DARK !!!

    Given text Highlight colors are too dark. Needs to add brighter Fluorescent colors. And pasted objects needs to be fixed and grouped optionally. Where a big pasted object covers whole paper, I can’t bring menu and it moves needlessly.

    This used to be the greatest app. I used it daily. It has slowly stopped functioning, and now all I can do is read a PDF. No annotations, no adding text, no signatures. This app is junk. Don’t waste your money.
  • Why do I have to pay multiple times?

    By BLC35
    I have already paid for this app, why can I not edit pdf’s now? It’s asking me to pay again.

  • From best to worst

    By Paniusk
    This has been my favorite app since I discovered it, and recommended it to many people. But, now it became a nightmare. It keeps creating a second file (which are corrupted) for most of my files. Every time I open the app, files on iCloud have to be redownloaded again, this never happened before. And when trying to download them the app crashes. And it does so constantly. There is a constant shuffling of files, appearing, disappearing and then appearing, but only to be downloaded again. This has made it very difficult to use the app. Also, open documents don’t stay open as they used to. When you look for them on the open tabs on top they are not there anymore. I was counting on an update that would fix these bugs, but it seems that it’s only getting worse. I rearely write reviews, but it seems that reviews are helpful to know what userers are experiencing with the app. I hope these issues are fixed soon so that I can enjoy the great app PDF Expert used to be.
  • 9.99 for the app then another 9.99 to use the edit feature!

    By Fergie501
    I bought this app believing I was going to be able to edit PDF documents. Not happy that they want another 10.00 for the features I thought I just bought
  • Money grabbing developers.

    By Jatisimo
    I bought this app 2 years ago for $9.99. I used it only once, but now that I need to use it again, it is asking me to upgrade it and asking for $9.99 one more time. I have contacted Apple support. They told me that the developer had changed the app and there was nothing they could do. They too agree that it was not fair. They recommended me to write a review for the developer, so here it is...
