I’m annoyed that I paid money for this. It seemed to meet all my needs because I could annotate, bookmark, and mark the document. I was reading and taking notes in a lengthy TTRPG pdf I had downloaded. The PDF is legit and not corrupted, I got it from the manufacturers as a free download for purchasing the physical copy of the book. I had several bookmarks, notes, highlighted areas that simply didn’t exist after the app crashed. If it can’t handle or isn’t intended for 300 page docs it should state that somewhere. It’s a PDF, perhaps higher resolution, but still a PDF. The reason I’m not giving it one star is that the features do actually work, I could underline, highlight, annotate, add graphics, and it would save my bookmarks, but to what end if it crashes unpredictably without saving?! There’s no save feature, like most mobile apps, so one assumes it’s auto-saving, apparently not. Opening a PDF on it isn’t the easiest, the user interface is confusing. And it doesn’t seem to always lock in zoom, so it’ll irritatingly snap back to full page or worse change the page you’re on. This is minor, but I really want to discourage someone else from paying for this. I’ll continue to use it due to sunk-cost fallacy, but only for it’s page preview feature and go to page that’s also available on the free version of Adobe Acrobat. I’ve gone old school and am actually using physical bookmarks and post its in my actual book. I’ve yet to find a decent PDF reader for mobile. ### 1/5 — Не лучше стандартного. Не тратьте деньги *2023-12-31* Все тоже самое чтоти в стандартном приложении. Не стоит покупать ### 4/5 — CBZ Files *2019-02-26* Please add support for cbz files. ### 5/5 — Great for bead patterns. *2019-02-06* I am a beader. I was looking for a system where I could organize and store my patterns. This has worked well and so far my patterns have not disappeared. That has happened in other similar programs. ### 5/5 — Transfer *2018-01-27* Would like to know if there is a way to transfer my files from iBooks to PDF studio ### 2/5 — Another fail *2017-05-16* Can't even import a document into it from Dropbox! ### 4/5 — Organizing, Reading and Booking are great. How about Annotating PDF's? *2016-06-11* I purchased this app a while ago along with Scrivio Pro which I use all the time and love. I just recently started using the app and have found the organizing, reading, book marking and the zoom feature to be great. I really would love to see the incorporation of being able to annotate PDFs files. This really is a must as we move further and further away from pen and ink. I am willing to pay more for this feature, especially if it works as well as the other aspects of the app. Thank you for the good work thus far. ### 1/5 — マジでpdf reader *2016-04-15* みる以外に何の機能もない、無料のものでも編集とか出来るから有料のもっといいの使ってみたいから購入したが、残念です。こんな単純な機能で良くこの値段付けれるものだ。 ## Frequently asked questions about PDF PRO Files ### What is PDF PRO Files?
