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.
