more I use PDF Viewer on my iPadPro with the pencil. I extensively use highlighting with different colors being used to represent different concepts. In previous versions, I could simply change the color of an existing highlight by taping on the highlight and choosing the new color. With the latest upgrade, I need to: 1) Tap on the highlight 2) Choose “Style” from the menu 3) Choose “Color” from the next menu 4) Finally select the new color for the highlight This is a hugely negative in my productivity in using of PDF Viewer, so much so that I am looking for a replacement. Perhaps there is a configuration option that allows me to revert back to the previous style. If so, please make it more obvious. I would previously have rated PDF Viewer 4 or 5, but I am now rating it 1 since this is a huge issue for me.———————-Updated - I am raising my previous rating of 1 star to 5. Per the above, I complained about the change and the developer responded in version 6.2.2 to provide for easier color changes. Perhaps a small issue for mist, but big for me. More importantly, it gives me confidence that the developer is listening and open to accommodating customer feedback.

There are some apps that just click. You can’t quite detail why, you just know it when you’re there. This is one of them. It creates a sense of ease that allows your to focus on your material, rather than how to use the apps menus. At the same time, when you want more, the power is accessible. As a grad school student, I needed to really think about where I want to spend most of my time studying… I think I found a new home. A. Features to consider losing: 1. annotations navigator lists page groupings in ascending order but annotations from within those pages are in reverse chronological order. At the least, have them ordering in the same direction, or give options. (Being able to manually sort is a nice current option) 2. page navigator on the bottom. It takes up real estate and peripheral vision for not much duplicated value. Any need for icons to navigate are obviously in that menu. Most annoying, and others have already reviewed this, when your palm touches a page in a 1000 page textbook, you need to spend time trying to figure out how to get back. 3. The highlight feature constantly defaults back to the blue color, even between highlights. It’s a struggle. B. Features to consider adding: 1. ability to capture snapshots of portions of the screen into the annotations list. Say, if I lasso a graph, it will copy that small window to annotations. At least show images that are annotation in the list instead of “image” which isn’t useful. 2. ability to view bookmarks and annotations in a larger window to see more pages simultaneously while reordering and getting a sense of a concept as a whole.

Having used PDF Expert for a long time I’m ready to find something else due to the ridiculous subscription model and lack of integration with the Mac OS program that PDF Expert has. I tried about a dozen Apps and PDF Viewer was the most pleasant surprise! All the free features here compare with Expert. In fact I prefer some Viewer tools better: the Magic Ink pen, the highlighter behind the text, the full screen viewing with the tool bar to the side, and the ease of opening files (you can go back to the open tabs without opening another file), the Lighter “blend” mode for the pen and the very good color options too; great job! Only a few things I don’t like: 1) the lack of a favorites toolbar (or ability to customize it). Too many clicks to switch between tools. 2) The text highlight tool does not look as nice as PDF Expert. Lose the rounded edges and have a variable text height. 3) The lack of a lasso or snapshot tool (Goodnotes has one and it almost makes that App a better PDF editor than anything else!). 4) the ability to add/create pages from a scan with OCR. If the developers WANT to make something really worth paying for they should offer full ability to edit text and objects within a PDF (original text, not just user added text). Until then I’ll keep searching for the ideal PDF App.

I have been using this app heavily for many months now. It become my goto for reading and annotating research papers. Feature request: a) Please add a setting to use the file name as the tab name. I just don’t understand why this is not the default. Some journals and sites transform the pdf, so the title embedded in the pdf may be meaningless, or the author used a nonsensical name like chapter. I can’t control that, but I can rename files to have meaningful names. When I have 10 tabs open and none of the tabs are named after the filename, I am unable to find or copy that file a second time easily from a directory containing hundreds of files. b) In the share/export dialog, the label has very low contrast and is difficult to see. c) When in dark mode, the highlight drawn with the brush is not visible. It shows only in light mode. d) Please add an option to open file in existing window as new tab when I open a file from the files app. e) Had to write this into a review because the in app/on website feed back option was not found. Thanks a lot and keep up the great work. I promise I’ll be back with the remaining star.
