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.

Full featured, but confusing as well to use

I played around with this app at a friend’s suggestion and there are definitely features I like about it. But, my two biggest complaints are these: 1) Way too many frequent ad pop ups that try to make you buy into something. Note to developer: Give people a chance to try the program without all that confusion and distraction for a few days. It only serves to frustrate a new user when you’re trying to figure out if the app will work for you. And 2) When I tied my Dropbox to the app I expected to be making changes to file I was working on connected to Dropbox, not downloading and edited the file on this program. It defeats the entire purpose of Dropbox! I have several other pdf editors and readers and this is the first to separate the file from Dropbox.

Developer Response ,

Hello. Thanks for the suggestions. With respect to the pop-ups, users will see the pop-ups only when tapping on the locked features or you stored more than 10 files in the app. We offer free trials to users to try out the advanced features for free (You can cancel it before the trial ends.) As for the Dropbox issue, PDF Reader currently enables you download the file and save it within the app for further editing. If you want to sync the edited file to your Dropbox, you have to use the "move" tool in file management mode to move the edited file to your cloud (No auto-sync support yet). If you still have questions and other suggestions, please feel free to contact us at We'd be happy to assist you. Thank you.

Misleading. Not an Editor. Milks you bad!

What a rip off unless you use these features every day. Of course I just wanted to send a PDF fax of the tells me I must sign up through email to use this feature. So I entering all my account information and set up a password, I finally get to the fax options, import my document, ready to fax. But then I don't have enough credits! It wants 150 credits! No problem. Probably only costs a few dollars to send my fax. But when I press on the button to purchase credit, it doesn't allow me to purchase credit. It tells me I must buy a $20 per quarter membership. Fudge. I'm in a hurry! So I purchase the dang membership, thinking I could now fax. Nope. They only actually give you 80 credits towards faxing, but it cost 150 for a few pages! So now it wants me to buy more credits!

Don't waste your time like I did.
*And no where did I find the feature I was looking for to edit PDFs. This program is misleading. You can only annotate. There are several free apps with the same features.

3 Stars because it didn’t have the features it advertised and milk you for every dollar.

Developer Response ,

Hi, thank you for the comments. Firstly, we provide one-time payment for credits for the users who have large demand of faxing. You can purchase the credits by clicking on “Recharge” button in the faxing page. Second, the subscription option includes not only credits, but extra cloud storage and advanced features in app. Hope you can try them out. If there are any further questions, please contact us at We are always glad to help you. Thank you for your consideration.
