It looks natural and beautiful. Annual subscription would be worth it if only the developer was updating it to avoid frequent crashing. Because it crashes often leading to the lost of all stored files and requiring reinstatement, this product is not worth being in apple apps. It is frustrating. Either the developer is dead or just doesn’t care to help users. Too sad… I have to delete something that I paid money for—all because the developer is careless to update it. ### 5/5 — My favorite annotations app!!! *2026-02-28, version 3.0.5* Please keep this app going! It’s simply the best! ### 4/5 — Pen thickness *2025-05-14, version 3.0.5* This is the best pdf annotation app I’ve found. No nonsense. Seems reliable. Like workflow. Can’t get collaborations to connect. Need a finer pen stroke though. When exporting, in says ‘open in’ which is not good ui descriptor. Just name it export to get all the choices like save to iPad. ### 5/5 — Whoopee, another update! *2025-02-02, version 3.0.5* As a long term user of the Cabinet app I was both surprised and delighted to see that an update was available. Over the ten plus years I’ve relied on this app it has served me well despite having a collection of several hundred PDF’s, some of them 200mb plus in size. A handful of crashes have occurred and many times the app would only relaunch after a cold reset of the iPad. Hopefully this update will improve the stability still further. The one feature I do really miss is the ability to add new folders that will sync with iCloud. However, the folders I had already set to sync on an older version of this app still sync flawlessly. It is important to me to have all my PDF’s backed up. Perhaps the developer(s) might consider reinstating his feature? (Please!) I blushingly admit that I have had brief dalliances with many other pdf apps but this is the only one that I would marry - it is a superb app and used daily. Edit: 2/2/25 Delighted to see an update of my favourite app. The last update was very stable indeed. Simple intuitive design at its best. Thank you. ### 5/5 — Amazing app *2024-11-19, version 3.0.4* Love this app. I’ve used it for years and it does everything you could want. ### 5/5 — Legendary app in now on iPhone! *2024-11-09* Well, this was always my go to PDF reader on iPad. And even though it is not updated with new features for years, it is still miles ahead of many similar apps in terms of UX. And now suddenly it’s on iPhone! I do hope they bring back the iCloud sync functionality though. ### 1/5 — Useless *2024-06-19, version 2.8.12* The annotation feature is impossible to utilize. Don’t waste your $. ### 5/5 — I Love This App *2024-05-31, version 2.8.12* This app is great. I can easily organize, read, and annotate my PDFs. That’s all I needed and all I wanted. The interface is simple and uncluttered, and performance is great on my iPad Air M2. Perhaps the best part of this app is that it doesn’t require some stupid subscription like all the other PDF apps out there. I just wish I could pay the dev somehow :) If the author is looking for something to add to make the app even better, adding native support for SMB connections to home file servers would be awesome. Thanks! ### 5/5 — My Go-To !! *2024-02-04, version 2.8.12* I absolutely LOVE this application. I use a lot of digital bead patterns and it has been my go-to application for these and other patterns as well! It’s simple design makes it uncomplicated for crafters and recipe saving as well. My only suggestion is MORE! I would like it to work on my apple laptop and desktop as well. Good job! ### 5/5 — I never write reviews, but I depend on this App! *2024-01-28, version 2.8.12* I’ve been using this app to save PDFs including recipes, CVs, and other documents of all kinds. I love that they can be annotated and shared with/without my notes, and saved into folders so they can be found again. It’s one of the most intuitive apps on my iPad. In fact, I’ve got so much important stuff in there that it occurred to me I would be lost if I couldn’t access it! Please tell me if you ever plan to discontinue it, which I hope won’t happen. Some suggestions for developers- it would be fab if docs could be shared to social media straight from the app, or be put on a clipboard so they could be pasted wherever. Also, make it usable on an iPhone? Although I know it would be difficult to read/annotate etc, I would find it useful to be able to save straight to the app from my phone rather than having to email myself docs to later save on my iPad. In the meantime, I thoroughly recommend it and urge you to try it!! ## Frequently asked questions about PDF Cabinet ### What does PDF Cabinet do?
