  • Nice app

    By ChristFollower002
    Nice app, but there is something kind of bugging me. I don’t like, how whenever I change how stuff is ordered, it changes it everywhere else. It would be nice if each place was independent of everything else. iCloud items could be listed by name, items in a folder in folder in iCloud, could be listed by date. Something like that, where each page could have its own order I think would be nice, instead of a single change effecting how everything in the app is ordered. Please add, to both versions, NOT just the upgraded version.
  • You have to buy this app to have a “privilege” paying another 9.99$

    By OwenYS
    Misleading . I PAID for the app not to be constantly bombarded with Upgrade to PRO nonsense. If this PAID version doesn’t provide certain feature just DON’T list it , hide the buttons and list a separate version. Horrible marketing decision from the developer and I’ll be switching to a different pdf editor .
  • Garbage

    By davomativ
    Using this app from my iPad and it does absolutely nothing you want it to. I’m deleting it shortly
  • Upgrade issues

    By salcde
    Unable to use since update. What happened?
  • Update???

    By 321GordonHall
    Haven’t been able to open a single pdf since the update. Would have given a four prior to latest update.
  • Conflicted

    By Brandon D.C.
    So I’m somewhat conflicted about what score to give this app. As far as functionality is concerned, 6 out of 5 stars is a more than accurate representation of the ease of use and feature list. My problem is with spending 9.99 on the app in the bundle and not receiving pro features. Once downloaded, another 9.99 purchase in app to unlock features you technically already purchased is so frustrating. Huge deduction for this money grab.
  • Most recent upgrade hosed the app

    By Cassilyn
    After trying every annotator out there, this has been my ‘go-to’ PDFs annotator for years, until now. I am a field engineer and my job requires me to annotate documents away from my office. Marked up my PDFs yesterday, only to discover that my mark-ups were severely altered in the app this morning, making them unusable. This was the case on TWO different devices. Had to go back to the office and print out the documents, so that I can now return to the field with pen and paper. iAnnotate, although a bit overkill, will be my replacement. You lost me, Readdle.
  • Can’t get this ap to load

    By Whata!
    Paid the fee and have downloaded it several times to only get the logo and then the ap closes.
  • Unable to view pdfs

    By -★☆☆☆☆-
    All PDFs are now blank.
  • Great app, but having problems lately

    By DRE0595
    I use this app on all of my devices without problems. It’s very solid and does what I need. Lately I have had problems with crashing when attempting to add outline items on my iPad. Since my iPad is my main device, it’s pretty debilitating to not be able to outline large PDFs. This would warrant 4 stars, but I have not been able to send a message to support due to the website not working so I am leaving 3 stars for now.
