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 ### 2/5 — App performance *2026-06-19, version 2026.6* It’s a good app and I’ve been using it for a long time, but after updating the last version, editing on the pdf becomes slower and the app still glitches and closes the file. I hope this issue being fixed soon. ### 4/5 — Shaping up to be a serious competitor to PDF Expert *2026-06-17, version 2026.6* PDF Expert seems to reign as the king of PDF Editors in the Apple Ecosystem. Compare the number of reviews in the App Store. That’s because it’s good! However, it needs a serious competitor, and PDF Viewer is shaping up to be one. It’s not yet as polished or comprehensive, but I expect that will improve. I am willing to be patient because I appreciate that its developer, Nutrient, has more technical depth from its core business, which is PDF technical services to top-tier organisations, and has more commitment to the industry body, the PDF Association, and its ISO standards. (When I last checked, Readdle was not a member.) As a professional who works daily with PDFs, I need a professional PDF Editor. ### 2/5 — App flashes and glitchy *2026-05-12, version 2026.5* If it was fixed i would like this app. Its hard to use because everything strobes and flashes. ### 3/5 — Not able to open multiple pdf files in a single window *2026-05-07* I want to open multiple pdf files in a single window of PDF viewer application through multiple tabs. This was possible in previous iOS versions, but after the latest update I am unable to do so. Now whenever I open a pdf file all files are being opened in a new window and thus it is tedious to switch from one pdf file to another. Earlier all pdf files can be opened on same window through multiple tabs. Please solve the issue ### 4/5 — Only one thing between this and perfection *2026-03-20, version 2026.3* I love this app, it is so much better than Preview and it makes reading things on my iPad and Mac a dream. My one criticism is that I would dearly like to be able to set the cover page PER FILE, rather than as an app-wide preference; some of my PDFs have cover pages and some don’t! But it’s a minor point in a brilliant piece of software. ### 4/5 — Needs some features *2026-03-13, version 2026.3* I really love the app, but it needs two important features: Please add a sticky note system and the ability to add multiple color options directly to the main toolbar. Changing pen colors currently takes too many taps! ### 4/5 — Very good PDF viewer, but needs a sidebar *2026-02-25, version 2026.2* I’ve been using this app for many years. It’s a very good PDF viewer in my experience. It’s been very stable and buttery smooth. My only suggestion is the inclusion of a sidebar that gives the option to show the PDF table of contents or page thumbnails, with a hide/show option, that can be placed on the left or right of the PDF based on user preference. ### 3/5 — Pls fix the bug of full screen alignment of toolbar and status bar *2026-02-21* There is an annoying bug which can be creataed by following steps:- first opening a pdf, then opening the tool bar, it floats with some little distance in the top margin, then swipe home and then open the app aagaain, you will see that the status br is overlapping with the top tool bar. PLEASE I urge the developers to fix this bug in the next update, i really love this app, pls for the coninece fix this annoying bug that iss ruining the experience ### 3/5 — Flickering *2026-02-21, version 2026.2* A great app other than PDF view constantly flickers, meaning it’s unusable. Lot of potential. ## Most critical reviews (10 lowest-rated) ### 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. ### 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! ### 1/5 — Nope *2026-04-13, version 2026.4* Welp, I wasn’t able to easily figure out how to fill out a pdf. This should pop up when you put your finger on a text box. I should have to decipher a bunch of symbols to make me be able to do that. I detest PDFs with all my heart and wish that somebody would make a replacement. It is pathetic we have to deal with this ghetto technology in 2026 A.D. And I will never pay to rent a tool like this. It should be a one time payment. If there is a major update, sure, I’ll pay for that. But the idea that you get paid forever for something like this? No way. ### 1/5 — App Not being fixed *2026-03-31, version 2026.4* Signature options only show up in white now and updates won’t sync to OneDrive at all ### 1/5 — The worst *2026-02-21, version 2026.2* This is without a doubt the worst pdf editor I have EVER seen. It is totally worthless. Thanks for vetting worthless apps, Apple! ### 1/5 — How do I suggest a feature or contact support? *2026-02-19, version 2026.2* How do I suggest a feature or contact support? I’ll change the star rating or delete my review when somebody has responded. ### 1/5 — No customer support *2026-02-16, version 2026.2* I am trying to reach out that pdf viewer is not working fine to get measurements and their tool is not selectable when i tried to as i have subscription. ### 1/5 — Flickering if the List of Content tab open *2026-01-30, version 2026.1* I used to love this app for pdf annotation. But for the past one year there has been annoying bug where the screen flickers whenever list of contents tab open. I have to force close the app and relaunch to stop flickering. There is no improvement for one year…that’s disappointing. Time to find alternative. ## Most praised reviews (10 highest-rated) ### 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 ### 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.

How can I fix this problem? ### 5/5 — 可以画画、可以打字、还可以加照片。 *2026-04-20, version 2026.4* 好用 ### 5/5 — Great *2026-04-15, version 2026.4* The app is great for viewing and writing on pdfs and super convienient for doing pat test papers it is a great study tool if you use it for studying 100% would recommend ### 5/5 — Great *2026-03-02, version 2026.2* Fantastic ### 5/5 — How do I suggest a feature or contact support? *2026-02-23, version 2026.2* I’ve been using this app for many years.

No more need to print the patterns. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
