Feature request. *2026-08-22, version 2026.10* 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. ### 4/5 — My PDF viewer *2026-08-19, version 2026.10* I greatly enjoy this App, I have been using for years now. The features are very useful, the App helps me navigate easily on documents, it can also be enhanced with color options in the “note” feature. I definitely recommend it, it’s one of the best out there when it comes to working with PDF documents ### 1/5 — It will delete your files! *2026-08-14, version 2026.10* Don’t put your PDF files in the default folder because if you uninstall the app, it will delete the contents of that folder. I don’t RENT software. I subscribe to magazines and newspapers. Their content completely changes warranting a subscription. Apps, once released don’t change ‘completely’, so a subscription NOT justified nor ethical. Just cheap capitalism and dumb people. ### 5/5 — Great but one problem *2026-08-11, version 2026.9* It’s great but my last page of notes after a session when I open it up again later isn’t saved. Very frustrating. Please fix ### 1/5 — Lame corporate model *2026-07-13, version 2026.8* I can’t stand companies who don’t provide a way to ask a question about the product. They stiff arm you; you only get what they publish. PSPDFKit FAQ doesn’t even allow you to search it. There’s no help doc in the app. I love the app, but if I can’t get answers to my questions, through the app, I’ll be tossing it in the trash. Not to mention, the new “fad”, is for companies to get you onto a subscription. This companies communist business model makes me sick. You don’t own it, just fork over your money. What a waste…I’m better off using Apple’s mediocre Preview app. ### 1/5 — This app is blocking its best feature. Poorly designed! *2026-07-06, version 2026.7* This app is the most limited app that I've ever tried. It's crazy. The very reason why I have this app downloaded, which is the page curl for PDFs, is blocked partially by the top window especially if you have other PDFs opened. It doesn't allow you to correct the fitting size. Why would you have a page curl feature that's blocked by the navigation of tabs and not allow a person to correct the fitting so that they can enjoy the page curl? It's nonsense. ### 1/5 — OMG! You deleted all my PDFs!!!! *2026-06-30, version 2026.7* Oh! My! God! You monkeys DELETED ALL MY PDFs! You’re stupid Data/Documents file had grown to 3/4 GBs (Apples scam causing big memory devices to be sold for more $$$ so I deleted it and reloaded it. You idiots deleted the folder with all the PDF files. Hours and hours of Internet research WASTED by you idiots! Not even intelligent enough to ASK first stupid! ### 5/5 — A more professional alternative to PDF Expert *2026-06-28, version 2026.7* Professionals know the importance of professional associations and industry standards. Nutrient is a member of the PDF Association; PDF Expert’s developer was not, as far as I last checked. It means that Nutrient is more involved in the wider PDF industry, including the ISO standards for PDFs. Nutrient prices the Pro version of this app very reasonably because it showcases their core business: providing PDF software services to top-tier international organisations. I like this app’s clean and simple UI. ### 5/5 — A more professional alternative to PDF Expert *2026-06-25, version 2026.7* Professionals know the importance of professional associations.

I hope this issue being fixed soon. ## Frequently asked questions about PDF Viewer by Nutrient ### What can I do with this PDF viewer app?
