## KyBook 2 Ebook Reader Reviews in United States

### ***** "Using many years"
I using Kybook started from first release. Always worked just perfect. Stable and solid. Good for iPhones and iPads
-- Editiob, 2025-08-14

### *---- "False claim of ability to edit color themes. Annoying page turn animations."
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.
-- Ariel J. Transparentpseudonym, 2025-05-04

### *---- "Spyware!"
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.
-- refusinganickname, 2025-04-13

### *---- "Бесячее сообщение «отключить рекламу»"
Бесячее сообщение «отключить рекламу» . А рекламы никакой и нет, за что деньги тогда платить? Только чтобы это сообщение пропало?
-- mycnik, 2025-03-23

### *---- "Не работает"
Книги не получается читать. Все вылетает и требуют купить pro подписку.
-- Ptsha, 2025-02-27

### ***** "Zybus"
Excellent reading app Thank You
-- znajdus, 2024-09-12

### *---- "Asks for paid upgrade"
This app is not working any more
-- Spirula 2010, 2024-08-19

### *---- "Ads for version 3"
No bug fixes and periodic popup for up-sell.
-- Paid ads, 2024-04-23

### ***** "Great lightweight app"
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.
-- Ann Othernick Name, 2024-04-05

### ***** "A GREAT app!"
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.
-- Hal_Lightman, 2024-03-28

### **--- "Got it paid for it"
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
-- ASL4U, 2024-01-28

### *---- "Restore purchases doesn’t work!"
I bought that app few years ago from this Apple ID, but the restore doesn't work!
-- aoibluevi, 2023-12-13

### *---- "Spyware!"
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.
-- refusinganickname, 2023-12-02

### ****- "Go KY!"
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.
-- Gorgeous Val, 2023-10-10

### ***** "Works like a champ"
Love the iCloud integration and the way it saves where I left off reading the book and continue from another idevice
-- RickyMiki, 2023-06-10

### *---- "Kybook 2 is broken"
I am no longer able to select, rename, move, etc any book. I hope I can find a way to export the hundreds of books I have stored in this app to another ebook reader (except Kybook 3)!
-- kbklarry, 2023-03-11

### ***** "What s not to like?!?"
I would say let me count the ways, but I ll just go with what s on top of my brain: easy to read, can listen to uploaded content, reasonable cost to upgrade, choice of languages, easy to post reviews of books, et cetera. 

Live Life, 

John Shrek Walters 
Sent from my iPhone
-- Jones Traveler, 2023-01-15

### *---- "Abandoned"
It was a great app, but unfortunately it is completely abandoned by the developer for 3 years. Don't bother buying subscription - synchronization doesn't work and not going to - site certificate expired.
-- Konst_ms, 2023-01-06

### **--- "Ads & no pencil"
Nothing other free apps like ebooxs cant do better, for free. no pencil support. Ads and more ads. Buhbye
-- Philosopher's Cave, 2022-11-01

### ***** "Books"
I am very satisfied in reading the books . They make me feel easier reading them because of them being clean. I don’t worry about being subject to profane words or extreme violence.  I relax and enjoy the the book more that way. Thank you for this. I also like to read very old books from the 1800’s and early 1900’s . Love going back in time.  Thank you again for making this web sight available to us all.
-- Molly Doody, 2022-10-25
