Contact PDF Viewer Support

I use the app to read pdf textbooks, that’s it 1) My biggest gripe is the subscription. I won’t pay a subscription for viewing PDFs, that’s ridiculus. There should be something in the middle, a fuller featured low cost one time pay version. Some of us don’t need most of the pro features. Some of us don’t need any editing features whatsoever..we just need a few of the basic UI features you have unfairly used as a lure to get us into a subscription. A few simple features is all I want, like turning off the annoying horizontal thumbnail bar at the bottom of the page, are only available with a subscription. What? 2) the performance of the app with large pdf files is not as buttery smooth as I would like. FYI, I’m using a 2018 iPad Pro, a very powerful device. Is the limitation hardware or software? I don’t know. Other than that, there are a few features that are unique to this app. One lets you easily jump back and forth between two pages you visited no matter how far apart, for free.

The reason I gave this app one star is because how it handles app switching on iPad Pro. When annotating a PDF file in this app, I cannot safely switch to a different app. If I ever try to use the screen bottom app switcher, inevitably, I will touch the page slider bar at the bottom of this app. Then the page I'm viewing will inevitably jump to other pages. This design flaw is so annoying. I have to stop using this app and go back to PDF expert for better user experience. I will update this review to 3 stars if the developers fix the design flaw I mentioned above. (Update: It's fixed now. So the review is updatedto 3 stars as I promised.) And BTW, the line drawing function in PDF expert is far more superior than this app: Lines in PDF expert will automatically align to horizontal or vertical direction. And the lines will even align to themselves. These whole bunch of features are missing in this app. Yet this app charges us yearly? Broken deal. I will update the score to 4 if this app charge once, and offers the same experience and functionality as PDF expert. And update it to 5 if this app has the same wonderful Mac OS version as PDF expert. Till then, this app is overpriced and sub-functional.

First of all, I really like the design of this app vs Adobe or other PDF viewers out there. I like it’s simplicity and what the free option is offering. However, there’s some minor but rather inconvenient details. 1. I use pencils with multiple colors for taking note, and I really want to have multiple pens in the tools windows of different colors. Right now, I have to open the color windows, find that new color down there, and then click again to close it, which takes more time than I used that color (to write the pronunciation of a foreign word). Can you enable customizing tool bar? I just want to pin multiple pens to the toolbar. 2. Word selection boundary is strange. When I long press to select a phrase (in Japanese), it often select 5-10 words on that line, and the boundary is somewhat unclear, and I had to adjust both sides. Other apps seem to do better in this regard, so I guess you can call the same API provided by iOS? I’m not sure if this is some unintended behavior of some Smart Selection guess algorithm that falls apart in Japanese language, but sticking to the basic one or two character seems a much better solution to me. Thanks for reading through it, and I hope this will make it to the developers.
