Editor Review

You are Downloading Cool Reader Latest APK 3.2.501. Last Updated: Feb 25, 2021.

Cool Reader developed by Vadim Lopatin is listed under category Books & Reference 4.3/5 average rating on Google Play by 260383 users).

Cool Reader's main feature is Reading books in epub, fb2, txt, doc, rtf, html, chm, tcr, pdb, pml formats..

Cool Reader apk was fetched from play store which means it is unmodified and original.


Quite possibly the best ebook reader on Google Play.

Has quickly become the best ereader on Android.

Very comfortable and user friendly app with a lot of functionalities.

You guys took the best epub reader and made it even better.


It would be perfect if it can read pdf files too.

Uninstalling since it is not working with pdb files.

Sometimes crashes and cant open books when they worked before uninstalling.

It won't open files stored in Google Drive without erroring.

Good application but table of contents not working for chm files.

Cool Reader doesn't recognise the SD card.

One flaw: couldn't open PRC file that's larger than 800 kb.

but the latest version force closes when i open a book.

I wish if this reader supports pdf format books also.

But can't get to table of contents topics of chm files making it useless.

Good reader but doesn't support Japanese.

now it just crashes when i try to open any book.

now it just closes loading books.

The latest version cannot open mobi format books.

the only disappointment is that it can not open pdf files.

Nice reader but lacks library / book shelf.

Also please add PDF and this would be the best reader.

Please tell me how to turn off the auto-rotate.

Option to choose text encoding would be great.

Please support chinese simplify character.
