  • Find something else if you need google drive sync

    By gzhang8
    The google drive sync is not fully functional. It deletes my files when facing file conflicts. Technical support cannot find a fix after requesting multiple logs. I am a dev as well. To me, it’s just because they don’t care too much and don’t want to spend much efforts on it.
  • Updated version doesn’t recognize my previous purchase

    By Bobby249
    I purchased the pro version and used it frequently. The updated version is trying to sell me the ability to edit documents and doesn’t recognize that I have bought this before. This does not make me happy as I need to edit documents right now.
  • Wait....What???

    By Stormrider770
    So I have been using this app for years and it has always been there for me. I purchased the pro version and all was well for a long time. Today I opened the app to fill out a contract and it informed me that I have to purchase it again. Really??? Not happy with this!
  • Ripoff

    By hjazzi
    I paid $10 to download it and then when it downloaded i have to pay another $10 for pro. Total ripoff!
  • Really good app

    By Smokie Budding
    I’ve been using this for about a month now and I’m loving the flexibility of the features. They all work well and are easy to get a grasp of relatively quickly. The one thing I’d like to see in a future upgrade is for it to recognize (and add) form fields. (If it can add form fields for text already I apologize. I haven’t found it) I think that would make it perfect.
  • Great app!

    By abc_1111
    Organize, annotate, highlight, make notes, merge. Everything I need! It is a “pay once and own it for life app”, not a subscription service so really good deal. I did not purchase nor need the premium features. Still a very good app. Tried other free and paid pdf apps but I always come back to this. People leaving poor reviews can not grasp the idea that additional features requires additional payment.
  • What?????

    By Kiki3366547
    I just paid 10 bucks for this app and it doesn’t do anything unless I upgrade again? What a scam.
  • Great

    Perfect appp
  • Great app, but unstable lately

    By danis77
    I have been a big fan of this app for years, but in recent months it has become unstable. It freezes frequently, and sometimes my Apple Pencil annotations would disappear.
  • App is good, but it’s hard to stomach another $9.99 after buying the app for $9.99

    By Derek M
    I got in the app and saw there was a $9.99 “upgrade” to edit PDFs. I thought it must be a mistake, as certainly I got the “full app” for my original $9.99. Turns out you don’t get the ability to edit PDFs for that price. Sours me on the app at large as this feels a bit like being nickel-and-dimed.
