  • Best pdf app hands down

    By BobHamlet
    I do a lot with pdf files and this app makes it easy.
  • Great app, but...

    By MSBCRR007
    Love this app, the only thing that bother me is sometimes, depending on what app your working in when you go to export a file into it, it's not in the list of app options.
  • Love, Love,Love the PDF Expert!!!

    By Truthistheword
    What a great App! Keep up the good work and the tips and the connections to the other features is an excellent time saver. This App is GREAT!
  • Fantastic App!

    By jasiek_5
    I have been using this app since 2013 and it has been fantastic. I t has completely removed my reliance in Acrobat and Preview in my Mac. Love the ability to complete forms and sign documents and send back and forth. Filling out forms has never been easier and I have converted many of my traditional forms and processes to PDF and now work in this environment whenever I can which has greatly increased my productivity. Great app! Recently got the Mac desktop version and it has really been fantastic as well.
  • Pay for app, then Pay again to use

    By Hobbes8585
    A little mad that after purchasing the app I needed to spend another 10$ to edit PDFs. However, I use another readdle app that is an absolute godsend. So I Will spend that money for the company for there other app.
  • Excellent

    Excellent program, very happy
  • Hands-down THE BEST PDF Wrangler for iOS⭐️⭐️⭐️⭐️⭐️

    By Rob Sketcherman
    YES!!!! get it. If you use your iPad for work, you’ll have absolutely no regrets. Guaranteed. I have used this app for years now, and the recent update which gave us 2-up viewing (see both pages of a PDF book at the same time) makes this the only PDF app I need. I depend on it, use it almost daily on my 12.9” Jumbo Pro, and HIGHLY recommend it to everyone who asks me about iPad apps👍🏼. PDF Expert (+PDF Converter) make such an amazing team that I’d recommend it anytime over trying to do the same things on desktop/laptop. This app has the best balance of truly sueful tools, without cluttering the UI with unnecessary, seldom-used features. TOP REASONS to use PDF EXPERT: ⭐️ a clean, elegant, logical User Interface ⭐️ cloud intergration with all major services ⭐️ excellent, natural hand-writing engine ⭐️ makes signing documents an absolute breeze ⭐️ fabulous annotation capabilities ⭐️ excellent tools: 2 highlighters and 2 pens (just enough) ⭐️ customizable colors, pen opacity etc, shapes, text ⭐️ 2-up page view: finally! View PDF books properly! ⭐️ edit pages in your PDF by adding, moving deleting, merging ⭐️ add stamps or import custom PNG files! ⭐️ ...and most importantly, STELLAR support. My experience has been someone getting back to me within 24 hours. Readdle‘s team constantly improves the app, issuing timely updates with great features. The In-app purchase which allows further levels of editing is SO well-worth the purchase too! In a time when many apps are moving to subscription models, Readdle has kept in-app purchases a 1-off, reasonable flat fee. My fav features for that $10 in-app purchase: ⭐️ Edit the TEXT in PDFs you receive! (Just think of all the time saved by being able to fix stupid typos in a snap without needing to open the a word processor, edit, export etc.) ⭐️ Edit / add / replace images in PDFs too! (And they even give you 3 options in resolution) Thank you Readdle, for a truly remarkable, highly useful app! I teach iPad creativity and productivity, and sing your praises every chance I get. Well-earned 5 ⭐️⭐️⭐️⭐️⭐️!!!😄
  • Highly Recommended, but after last few Updates …

    ‘PDF Expert’ • (iOS)App – by: Readdle! Highly Recommended, but after last few Updates … Loved using the App for everything, but since the last few Updates … been having issues with the App; bumping me out or freezing. I’ve sent eMails to the Readdle Support, but haven’t heard from them! Otherwise, the App ‘was’ fantastic! If anyone knows how to solve these issues, let me know, please! Thanks for your time!

  • Great app

    By Mwesha
    Great app for annotating PDFs though at times I face challenges with inking capabilities. Integration with other Readdle apps make it fluid to use if you are already invested in the ecosystem.
  • SCAM!! wants to make me pay for the app twice!!

    By Burned Customer
    Update! Still a scam. App got stuck for 2 days asking for an update very buggy and didn’t want to open files. It said I had purchase again which I did because I needed to see mi docs. I BETTER don’t see an extra charge for this app that I have bought 2 times already. It seems that every time they try to “upgrade” they Always come back with buggy code and app freezes and you have to delete and download again/purchase as it acts as if one hadn’t already paid for this sad app. Looking for alternative. STAY AWAY.. for your own good. Don’t get burned. Recently purchase this app for $10.81 for all advertised features that I thought could use to edit pdf files and now, barely a week after app purchase is asking me to upgrade to “professional” and won’t even let me open any more files. Reporting this to Apple as well. Stay away if you don’t want to get burned!!
