  • Didn’t know I needed it...

    By Damon_Williams
    Until I needed it. Had a mission-critical assignment to quickly edit and distribute a baked-in PDF. This app helped me pull it off rather seamlessly. At first, I thought ten bucks was a little steep for this ‘superpower,’ but it absolutely worked when I needed it to absolutely work. To put another way: ten bucks is a steal, considering what the resulting drama would have been from not having that PDF ready.

    What happened to PDFOffice?! Please I am begging you to add into Expert, the ability to add/edit forms like office had! It separated readdle’s apps from all others
  • Disappointing

    By Junebaby25000
    I use to love this app. But now it keeps crashing, even when doing a simple task as filling out a pdf file.
  • Waste of money

    By Austin’s Daddy
    Doesn’t work correctly on iPad Pro and can’t connect to cloud storage. Save your money and keep looking for a new app

  • App bugged and deleted important file from cloud

    By sabdaccamax
    Worked 6 hours on a document and this app bugged and deleted the file. Such working tools should never bugg like this or at least have a recovery system. This makes this app useless as it is unreliable.
  • bait and switch

    By Ksulli81345
    I have no issue ever buying apps. I actually prefer to pay for my apps and get features and no ads. However I was a previous user of this software and needed to add it to a new Apple ID and paid happily. On top of this I have been using Documents and love it so it made the purchase even easier the ability to gain a new level of control over my pdfs. Then the kicker the second i spend money I’m greeted again by another purchase telling me if i want the features in the app i just spent money on I have to spend more money. I don’t mind spending 10-20-100 dollars but don’t tell me i’m getting something and then try to charge me again.

    Excellent app. Very easy to use.
  • Hello Readdle Please fix

    By Phansindia1
    I am just upset with Readdle Inc. Because Their apps are they play a vital role in freezing iPads time to time and sticky onscreen keyboard with missing keys. I own iPad Pro 12.9 WiFi and LTE 256gb model. The first app I install is Readdle paid apps and free DOCUMENTS. After that, I installed many other apps, but they are freezing my iPad time to time and onscreen keyboard missing keys while I type. I was thinking it is a hardware problem, so I tried every single thing possible that mentioned on the internet nothing worked well for me. I reinstalled iOS using iTunes several times and installing back all the apps the same thing continued, but I didn’t realize until yesterday day, I reinstalled iOS again because I was frustrated with iPad performance. After all, I reinstalled and setup as new IPad as usual, but this time I didn’t install Readdle apps so I checked if the screen freezes and onscreen keyboard will function well or not. GUYS BELIEVE ME THIS TIME EVERYTHING WORKING WELL AS IT SUPPOSE TO BE, but I want to install Readdle apps again just after 5 min installation screen started to freeze and onscreen keyboard started to stick. All I want to say is if u have any problem with iPad reinstall the iOS with iTunes and use without installing any apps use the stock apps and see if the problem reproduce if not means these apps are the ones making our iPads basically useless. I HOPE Readdle will fix this issue. I will post a video on YouTube as well so that others will know what documents and it’s sibling apps doing to their iPad. I read many online communities having this issue; I guess most of them using Readdle apps.
  • Love the features but how the $%^&& do I export

    Send button does not light up on emails. I’d give the a 5 star if emailing or help features easy.
