Reviews From google play store

A really good reader, I've used it for quite a while and been very happy with it. Lately for some reason it has stopped displaying book covers even though it's set to display them. I haven't been able to find the problem and it detracts from the apps appeal.

Still the best customizable open source reader after all these years.

Great app but recently book covers on epub books stopped to display, please fix this and i will put 5 stars

After this latest update the book covers no longer show in the browser. Please fix

Great reader. Would be nice if we could import/export settings. Also, the covers on the books that I added before the recent update no longer show up in the library, but the books I added after the update show covers. Did the cover directory change? Even with its bugs, I prefer and recommend this ebook app over all the others.

Perfect. Just one slight problem. When using read aloud next button doesnt work correct. Selected text jumps ahead of the actual reading line, making it very hard to fast forward in case you want too.

Perfect, I tried many different readers, Cool Reader most simple and really cool. *Day/Night reading mode (you can choose yourself), * Letter size *Bookmarks/pagemarks and more and more. I ❤ it xx

Great ebook reader, I wish it had some settings button while running TTS. I'm having books in different languages and it takes a while to change TTS settings in system settings, restart Cool Reader and then start reading text.

I like this app but since the last update the app is not saying my place in the current book I am reading join closing and then reopening. Mei ther does it save bookmarks created in the current book. Any hope of this being fixed soon? Am a fan of this app and hope jtt is fixed soon. FYI this problem occurred only since last updated this app.

It took a fair bit of time to configure it to my preferred look and feel (because there are sooo many options and the default settings aren't always that good), but once I got there, it was worth it. Not perfect (eg no in-app PDF support, can't annotate bookmarks), but the best ebook reader I've come across.
