だめだこりゃ
2026.9.23追記 評価5→3
アップデートの度に使いにくくなる悲しきアプリ。文章や画像を1ファイルに詰め込みすぎて500メガを超えてくるとアプリが頻繁に落ちます。無駄な機能入れずに昔のように軽くして欲しいです。グッドノートに乗り換えようかな…。
高校〜大学まで6年間使い続けています、とても使いやすい良いアプリです。録音機能（挿入→サウンド）はかなり便利で、講義中に音声ファイルをスライドごとに埋め込む事ができて、復習の際とても役に立ちました。
不満点を挙げるとすると
①PDF閲覧中に表示設定を縦スクロールにしていた場合、右端のスクロールバーを誤タップしてしまいがちでかなり邪魔です。ありがた迷惑な機能なので、このスクロールバーはオプションで表示オン/オフ切り替えれるようにして欲しいです。
②ページ閲覧中に右上を誤タップしてしまうとブックマークのオン/オフが切り替わるのもやめて欲しいです（せっかくタイトルつけて並び替えしたブックマークが、たったのワンタップで無くなってしまう泣）

Issue with the new interface design
Hello, I received the new update, but the app interface is now poorly designed. The old design was better, more comfortable, and more user-friendly. I hope you will fix this as soon as possible in a new update, as I love this app and can't do without it.
The new UI is too ugly!!
The new UI of the PDF reader is too ugly, please change it back! Or at least add an option for users to the change it back to the old UI!!!
Layout Changes
This is the second time they’ve done layout changes and removed actual good features, it’s slo,y getting worse and worse to use id recommend finding a diff app before this one gets unusable. I’ve been using them for almost 5 years and I’m done with their awful changes so I’ll be looking for a new one myself.

Pencil Problems
I have 3 iPads and the pencil tools only come up on one of them when you squeeze the Apple Pencil (they are all set up identically), and the toolbar on one of them crashes randomly, which requires a restart. The AI slop is awful, and burying delete below the fold on the selection tool is frustrating. This app used to be good. Now it's clunky.

Add a setting to disable liquid glass
The new UI is terrible and tiring to my eyes. Even Apple allows to modify liquid glass in ios27 but u don't?
Not happy
Very unhappy customer here! I paid for this app, and it dit what it was supposed to do very well. No, it will no longer do what I paid for it to do, unless I pay more for it on an ongoing basis. I am going to delete it now.
Exceptionally Helpful
This app makes many projects easier, cleaner in appearance and much more efficient.
Presenting feature gone!
Before the iOS 27 update, whenever I conecetd an external display there was a “presenting” mode that would mirror my PDF with extra features, but now its gone…
Sep. 15th update broken
Since the iOS 27 update, the presentation view is broken. Instead of showing only the current page to the AirPlay receiver, it only enters the “limited interface” view, and still shows the editing interface and swipe page transitions to the audience. I contacted support yesterday and have not yet heard back.
Before this, I had a minor bug or two, but was largely quite happy with the features and ability to customize the app.

Keeps getting worse and worse
From UI to buggy Dropbox integration to the subscription and paywall we feature nagging.
Corrupts PDFs
I have been trying to use this and I have the Pro version, but it keeps corrupting my PDFs when I edit them. I am opening from Files > OneDrive. At this point, I have to use another editor. I really hope this issue gets fixed soon.
Subscription !!
It’s a great app, probably the best, however, I would prefer to buy the app outright instead of subscription…
I paid extra years ago to have an unlocked version
PDF Expert is trying to get me to pay for a subscription when I paid to have everything fully unlocked as a bundle years ago. What a rip off. why is it that every time there is an update you take away my services that I had before when I bought the bundle years ago and paid extra so that I had no restrictions and I could convert my PDFs. Now I keep getting these stupid notices to get a subscription when I already had the service to convert PDFs unlimited. I will never ever get a subscription I'm glad a reviewer mentioned Ilovepdf.com, it's free. Your app pro bundle that I bought years ago is not worth paying for over and over, again and again and again! I don't do subscriptions for anyone

Simply amazing
One standout feature that this application has that a lot of other major PDF readers do not have is having the black mode which is very helpful to use in darker environments. It prevents a lot of eye strain. Apart from that, this has got a lot of tools and settings which would satisfy most of the demands that can arise out of a PDF. Overall, the best PDF reader for Apple devices in my opinion.

Monthly paiement mandatory
If you want to use it you are obligated to take a yearly suscription of minimum 69 $ …
Prow
This is a paid app
Nice
Great app. I use it for studying. But it would be great to improve handwriting and make it smoother.
Advertised as an editor
Cannot edit whatsoever. Must pay $50 for a simple edit.
PDF Edit
Everything is great except out of the blue when I am in edit mode, it identifies similar character pairs of letters and separates them from the text block and I have to go back delete the separated characters and re type them all if I can find them. This can be so annoying and has cost me considerable time especially annoying when I am in a hurry.
