### 1/5 — Horrible

*2026-08-01, version 10.3.4*

Horrible. All kind of signups just to try it. It’s also rentware so move on to a one time pay one

### 1/5 — Can’t select text in pdf

*2026-07-21, version 10.3.4*

Then what is the point?

### 5/5 — Great app

*2026-06-15, version 10.3.4*

Works well on my iPad 3. Love that it’s compatible ❤️

### 2/5 — Still don’t got what i want

*2026-06-07, version 10.3.4*

When you open the app there is this blast of “make an account, join premium, do this tutorial, do that tutorial” 😭.  What is this warm up mode i keep on seeing oh my god bro just let me open a pdf. I know it’d be a little ironic if I mentioned how unintuitive the features are after bashing the tutorials (is that what those were?) but it is just a pdf editor. It isn’t hard, but it’s weird how obtuse it is. It takes like 5 button clicks to add a bookmark. There are also like 4 toolbars. I’m really only keeping the app because it’s the only one that *allows* bookmarks. Wish they had an option in one of those toolbars to turn off the “Want to practice using a pdf editor before actually using it?”-button 😭😭

### 1/5 — Lost 3 hours of work! App on my laptop crashed.

*2026-06-01, version 10.3.4*

If I could give a -0, I would. Reached out desperately to support for help. I received a generic form email that stated they had an increase volume of support tickets this week. DO NOT purchase this app! Now I am starting my project over from scratch in tears.😢

### 5/5 — Extremely useful

*2026-05-22, version 10.3.4*

I have been using the PDF reader from quite some time and it is very helpful for my personal reading. There are many features which makes this app no less than other famous ones.

### 1/5 — Disaster

*2026-05-19, version 10.3.4*

This app is a disaster nothing works; tried text editing, crashed.  Tried file conversion, process hung, needed to restart my m2ultra

### 2/5 — Ok, 但是經常註解會上下顛倒，還有很多Bug

*2026-05-16, version 10.3.4*

大部分功能正常，但是經常會遇到每隔一頁，打註解文字會上下相反的情形，在iPad和電腦板之間讀同一份pdf也容易跑格式，並且經常無法把註解的文字正確列印出來，也蠻容易當機閃退，存檔也只有當關掉該文件時才會自動儲存，很多問題反應超過一年了人無改善

### 5/5 — Great job

*2026-04-18, version 10.3.4*

I use KDAN pdf mainly for converting images to PDF for cross stitching. It does a great job, especially since my iPad is rather old. Thank you.

### 1/5 — Don’t Buy

*2026-04-12, version 10.3.4*

I bought this app less than 2 years ago. I cancelled the subscription. It billed me for another year against my will. After they got there money they closed the account so I had no access to my account so I couldn’t use it even after they took a 1 year subscription. It has now turned itself on again and started billing monthly again. It is still within that year that the subscription should cover. In my opinion this is fraud. Do not buy this app Apple will not help you get you money back!!!
