Version 1.2.8
Wants money for features that were previously free, and still displays ads at the bottom. Useless.

Not free

Version 1.2.8
This app is not free. You’ll be able to read your books for a short while then pay $4.50 to upgrade to pro. Good for djvu files. Don’t know if the 4.50 is only for 3 months like KyBook3 is

Writing too small

Version 1.2.8
Need a way to increase font size

It reads for me!

Version 1.2.8
I love that this app will read for me. It means I can listen while doing other things. I can adjust the speed and the type of voice.
I wish I could annotate more in the app. Currently I use another PDF reader for that, but I would rather stick to one app for everything. Also, being able to organise my books into folders would be great. It’s free though, so I need to be realistic.
Great app!


Great oceans
Version 1.2.8
Fantastic reader with robust compatibility. Did not let me down yet!

Great App

Version 1.2.4
Great app. Simple to use and syncs across devices. Just what I was looking for.

Brilliant App

Version 1.1.0
This app has been brilliant in restoring old Kindle file. Easy to use, simply brilliant.

Doesn't support the one thing I need it to: .lit

Version 1.1.0
Sorry. Was hoping that because people raved about this being a replacement for Strata or whatever, that'd it do the same thing. I should have read the fine print.

It’s not bad, needs major improvements though

Version 1.1.0
This app is a stable ebook reader and has ok features. There is however a lot of work and tweaking to be done, and I have listed much needed improvements below:
- The sorting and grouping sub menus under each book menu is completely out of whack. None of these sorting features are working properly, with metadata or the file name itself. It would be good to have options such as sort by ‘date created’, ‘release date’ (of the actual file itself), and sort by file name. I am unable to sort my ebooks/magazines by any of these much needed options?
- Under the same sub menu there is ‘showing: book covers’, however there is no option to choose larger thumbnails? Say 4, 6, 8 per screen at a time?
- The favourites tab also makes little sense and needs to be more user friendly
- Under the main books category, these sub categories such as ‘top rated’, ‘sequences’, ‘subjects’, ‘authors’ and ‘tags’ need a major revamp. It would be wise to base your sorting methods of ebooks by following other mainstream content/ebook app sorting methods.
- In your app description it states you can sync with various cloud services such as OneDrive, iCloud, Dropbox etc, the problem is that even after I paid for the in app purchase I cannot see anywhere in the settings that allows me to do this?
- The apps themes options need an update with better colour schemes and designs..
- The ‘kybook’ and ‘dashboard’ sections are very minimal and could be updated with a fresher look ..possibly with featured ebooks or ‘what to read next’ etc?
- It also looks that the feedback/forum department has gone dead quiet?
I look forward to seeing big updates for Kybook 2 soon in the new year, as I do enjoy this app, so I hope this has helped :)

Good Job

Version 1.1.0
Finally a good replacement for Stanza, now if they could just get rid of the iPhone X swipe up bar when in night mode...

Fantastic Reader

Version 1.1.0
It really is a wonderful reader. Very clean but lots of options, if you like customising (I do!)


Version 1.1.0
This is what I want! This app offers handy dictionaries with tons of tools to make your reading experience better. Recommended.

Used to be okay

Version 1.1.0
I used this quite often until I had a mysterious green bar at the bottom of the screen that just wouldn't go away and obscured much of the reading space. I have moved onto another, better app which also happens to be what I use on my desktop as well.

A must get app

Version 1.0.9
I stoped using iBooks. To unreliable, syncing problems with books other than their books. No control over headers and margins - Painfull
Tried and deleted numerous book readers
KyBook is amazing. Full control great interface syncs with Dropbox perfectly.
2 issues.
Deleted books will reload if another view is chosen.
No resume function available. If a page is not bookmarked and you accidentally go back to another page ( happened numerous times) you can't go back to the page you came from.
Considering the functionality and number of positive aspects of KyBook it gets a 9 out of 10 from me.
Excellent app.
