Pleasantly Surprised by this App


I came across this app while searching for a quality PDF viewer/editor for my iPad Pro. I was surprised to learn PDF reader can not only read, but also annotate locked/secured PDFs. I'm not sure I want to purchase the app, but only because it seems to be subscription-based rather than a one-time purchase fee. This is the main reason I give the app 4-stars instead of 5. The other reason is more subtle when it comes to using the annotation tools (like when you select text to apply highlights, underlines, etc., you have to choose the action from the contextual toolbar rather than the toolbar on the side of the screen). However, I have only been using the app for about three days. So when I have a chance to use it longer and also investigate the pricing model, I may update or prepare a new review. In the mean time, get this app.

Hello. Thank you for the review. We understood your concerns. First, the Creativity 365 subscription plan offers all advanced tools and services in our main featured apps, including PDF Reader, NoteLedge, Animation Desk, Pocket Scanner, and Write-on Video. You can try it out for free before you decide to purchase. If you cancel it before the trial ends, you won’t be charged.
Second, we provide two ways for users to annotate PDFs. Select text and then choose the actions from the pop-up menu bar (as you mentioned). The other one is to tap on the icon on the sidebar and then tap on the content you’d like to highlight or annotate.
We will have a new update soon so please stay tuned! If you have any further questions or concerns, please email us at We are always happy to assist you.

Great App for making notes on a PDF


I use this app a lot, I'm in graduate school and I'm reading and making notes on academic articles constantly. This app allows me to do this from my iPad 3 and use it as a point of reference during class discussions.

UPDADE! 1/22...AVOID. Holding all my PDF files for ransom!


Update to below review. I DID register for free account as dev mentioned Before even writing review. It still did not work. Now it is working. There is obviously a delay in unlocking files. 3/5 stars as it was lots of wasted time and stress.
Holding ALL my PDF files hostage.

AVOID. Holding all my painstakingly highlighted and annotated PDF files for ransom unless i suddenly pay for subscription. It worked ok then next moment it won't let me open anything.

I cannot open any of them. Demands I pay subscription. I even deleted several very large PDF files to make room but that made no difference. AVOID!
