### 2/5 — Leider ...

*2024-04-21*

... unübersichtlich und umständlich.

### 2/5 — Got it paid for it

*2024-01-28, version 1.2.8*

No way to actually get books into it. No help. Sad.
There doesn’t seem to be a way to search. Can’t get any kind of menu down- swipe right will take you out of the book but I’d like to be able to get back to the TOC- or go to a different page. So not the best reader app for doing research or homework where you have to jump around- 
If the app can do it- there is nothing in the interface that shows you how- frustrating

### 5/5 — Incrível 🤩

*2024-01-07*

O melhor leitor de pdf que eu testei, por 14 reais este app faz o que apps caríssimos não é capaz de fazer, 100% recomendado

### 4/5 — Go KY!

*2023-10-10, version 1.2.8*

I have 3 versions of KY. KY1, this one, works on my Macbook, and I use it to read ebook formats that other apps can't open. It's full screen, text to speech, all the features I like. Ads, so I might spend $2.99 to support Mr. Bukreev.

### 1/5 — Не открывается, если не купить то, что предлагает.

*2023-09-07*

Не могу даже зайти, чтобы читать уже имеющуюся книгу. Появляется вкладка что-то купить. Жму «купить позже», пытаюсь открыть книгу и опять та же вкладка. И так до бесконечности.

### 1/5 — I’ve never liked this app

*2023-06-19*

Honestly I hate this reader, I totally resent when an eBook needs this format. KyBooks has adds constantly present while reading, it’s hard to navigate, the book is often obscured by the apps header… it’s just all round horrible and I can’t believe it’s got good reviews.

### 5/5 — Works like a champ

*2023-06-10, version 1.2.8*

Love the iCloud integration and the way it saves where I left off reading the book and continue from another idevice

### 1/5 — Автор приложения - мошенник!

*2023-06-02*

Приложение согласно описанию - бесплатное. Но когда запускаешь его, требует обновления до версии PRO.

### 5/5 — 希望有中文，并且能支持更多的格式

*2023-05-21*

希望有中文，另外就是希望支持chm等格式，虽然有别的格式的资源，但是手上有一份chm文档，感觉排版不错，不想转换了，希望能像win一样完美支持chm

### 1/5 — Spyware!

*2023-04-29*

I just opened kybook and was greeted with a notice that it had pasted from my browser! On what planet does an ebook reader need to read from the clipboard? On how many planets would any app need to read without user prompts? I can't believe iOS doesn't have clipboard security. There was confidential information I had neglected to clear on that clipboard. Thanks to these jerk developers and Apple, I feel violated.

### 1/5 — False claim of ability to edit color themes. Annoying page turn animations.

*2025-05-04, version 1.2.8*

My options for page turns are annoying page curl animations, annoying slide-to-turn (no single tap to turn), or annoying continuous scrolling where I have to carefully stop in the exact right place. No option for a one-tap page turn with no animations. 

In the settings it claims there is the option to edit existing color themes or create new ones. This is a LIE. I have wasted a bunch of time carefully selecting the text, background, etc. colors I want, only for this nasty little app to just throw away all my work once I close the editing window. There is no “save” button, just a “back” button that deletes my changes.

### 1/5 — Spyware!

*2025-04-13, version 1.2.8*

I just opened kybook and was greeted with a notice that it had pasted from my browser! On what planet does an ebook reader need to read from the clipboard? I can't believe iOS doesn't have actual clipboard security. There was confidential information I had neglected to clear on that clipboard. Thanks to these jerk developers and Apple, I was violated. Heh, and they think I'm going to download a more spyware laden version that wants to charge a subscription to display a document.

### 1/5 — Бесячее сообщение «отключить рекламу»

*2025-03-23, version 1.2.8*

Бесячее сообщение «отключить рекламу» . А рекламы никакой и нет, за что деньги тогда платить? Только чтобы это сообщение пропало?

### 1/5 — Не работает

*2025-02-27, version 1.2.8*

Книги не получается читать. Все вылетает и требуют купить pro подписку.

### 1/5 — Asks for paid upgrade

*2024-08-19, version 1.2.8*

This app is not working any more

### 1/5 — Ads for version 3

*2024-04-23, version 1.2.8*

No bug fixes and periodic popup for up-sell.

### 1/5 — Schrott

*2024-03-25*

Hatte die App zum Lesen von .djvu Dateien benutzen wollen. Leider nervt die kostenlose Version sehr: begrenzte Nutzungsdauer und obendrein noch jede Menge Werbung.

### 1/5 — Unable to delete books from the App

*2024-02-10, version 1.2.8*

Unable to delete books from the App. I hv upgraded to the Pro-version with the promise that all features will be available. This doesn’t seem to be the case as the App won’t delete unwated books which is a huge frustration. I will delete the book and when going to my books, the deleted book is still there. My phone is updated. Please correct this issue then I will rate the App again. Thank you

Still no change. Sitting with a bunch of epub books I am unable to delete. Will delete this app now. Was a waste of my money

### 1/5 — Restore purchases doesn’t work!

*2023-12-13, version 1.2.8*

I bought that app few years ago from this Apple ID, but the restore doesn't work!

### 1/5 — Spyware!

*2023-12-02, version 1.2.8*

I just opened kybook and was greeted with a notice that it had pasted from my browser! On what planet does an ebook reader need to read from the clipboard? On how many planets would any app need to read without user prompts? I can't believe iOS 15 doesn't have actual clipboard security. There was confidential information I had neglected to clear on that clipboard. Thanks to these jerk developers and Apple, I was violated.

Heh, and they think I'm going to download a more spyware laden version that wants to charge a subscription to display a document.

### 5/5 — Обратите внимание

*2026-05-12, version 1.2.8*

Замечательная читалка все отлично но на айфоне читает скобки. Борюсь с этим уже три месяца ничего не могу исправить.  Устанавливал и более новые версии такие как 3, эффекта нету. Может кто может помочь уже хочу продать этот айфон. На андроидах проблем ваще нету. Короче рекомендую отличная прога

### 5/5 — Perfecto

*2026-04-13, version 1.2.8*

Perfect reading app even using on ios 26

### 5/5 — Using many years

*2025-08-14, version 1.2.8*

I using Kybook started from first release. Always worked just perfect. Stable and solid. Good for iPhones and iPads

### 5/5 — Mon application préférée pour lire et sauvegarder mes Ebook

*2024-09-25*

Après beaucoup d’essais d’applications je plébiscite KyBook 2. Meilleur que le 1 et le 3. Je l’utilise tous les jours !!! Gilles

### 5/5 — Zybus

*2024-09-12, version 1.2.8*

Excellent reading app Thank You

### 5/5 — 适合看网漫

*2024-04-30*

纵向滚动看PDF文件几乎能完全隐藏边界，看网漫韩漫很合适
其他阅读器要么两张图之间有一道明显的分割线，要么不能宽度对齐屏幕，这个很好用

### 5/5 — Great lightweight app

*2024-04-05, version 1.2.8*

I like this app. It has a nice set of features, the ui is well designed, it seems like a pretty small file size, and it makes it easy to read pdfs and ebooks.

### 5/5 — A GREAT app!

*2024-03-28, version 1.2.8*

Most CBR readers won't work on old devices. But yours works great on my iPad that is over a decade old! I'm glad that I found this app. Because I use it all the time.

### 5/5 — 如何设置中文

*2024-02-20*

大家帮忙回复一下，怎么设置中文啊

### 5/5 — Parabéns

*2024-02-07*

Parabéns. Excelente app para quem quer organizar seus e-books para estudos, leitura e pesquisas. Comprei a versão completa.
