I loved the app and all features including the flexibility in layout. It supports all formats of e-books mentioned and there is also a night mode . Everything is FREE!! But it would be great if the page turning animation was made more realistic. That's the only thing lagging in Coolreader

Why ruin it? The app was working great! Now it won't even access my SD card. Why does every single developer mess up their product with so called "updates"?! I'd it works, leave it alone! Uninstalled...

This keeps closing while I'm reading i have to start over and skip pages to go where i left off its getting annoying. Im looking a different reader to use this is not for phones

From phone to phone I've rarely had problems using this app. I love it actually. That is until recently. I am using Xiaomi Note 3, Global ROM, Android 6, Miui, 8.2. The app doesn't recognise the external MicroSim. When you have over 1GB of titles it kinds sucks cause it's taking up quite a chunk of space. Hope it gets fixed in the next update.

Q70%
by Q####:

Books disappears from recent books all the time. Annoying. Try it only if you do not mind to search for a book on storage, then search for a page you stopped reading at least once a day.

F70%
by F####:

The best ebook reader I've used in a long, long while. My only personal concern is that it tries to open the same ebook each time I start the app, not the one I'm currently reading. When I deleted the book, the startup message is "Cannot open book". Then I have to press Back & then click on the book I'm currently reading, from the list displayed. Apart from this one frustrating thing, I absolutely love it. If a solution can be provided, I'd have no hesitation in giving it 5 stars. Cheers!

It has one major flaw. It can not read book files from the external micro SD card. Internal storage is no problem, but it won't even recognize that the SD card exists. Otherwise it is quite good for what it does.

Q70%
by Q####:

How difficult can be to implement SD card read access? I had this app on all my devices and now I just cannot use it with the book collection I keep on the card. Will come back with different rating once this is fixed.

This works well on my Samsung 4. I use it every day. It crashes once in awhile, but I have never lost any info. It's one of the few apps I've paid for - donated in this case.

by Q####:

Great application. But exists one negative feature. For Android 7 + miui 9 had no access to SD card at all. App shows notification that "application is old..."

Q70%
by Q####:

Was one of the best, highly configurable. Perfect for those who don't care to spend a little time preparing it for the best reading experience. Unfortunately, since android 7 it doesn't work anymore, do not recognize SD cards and do not link itself with epub fies. Those faithful to it have no other choice to migrate.

Q70%
by Q####:

It was the second epub app I installed and it's absolutely perfect. It has a simple clean interface and highlights and bookmarks with ease,which are the features I look for.been using it on 3 different devices since past 2.5 yrs.so I've used it a lot and it has rarely failed me(no apps foolproof). Best app for epub files.

Use Cool Reader 3 on my PC and have always loved it, but after installing this onto my Galaxy S7, and finding out it cannot read books from my SD card, I am going to have to abandon it and try something else... }:[

Has mind of its own. Messes with brightness lvls, rotates when in phone it's turned off and other small annoyances.

Y70%
by Y####:

I really love it. It is nice that you can customise just about everything you like! The only thing is, I wish you could synchronise your progress/bookmarks across all your devices. So I can read on my phone when I'm on the go and carry on on my tablet at home without manually entering the new spot. Would it be possible to do that at all? Perhaps with a log in. But otherwise this app is perfect! Always works well and a joy to use!

Q70%
by Q####:

This is my favourite eBook reader. It does almost everything I need. The only thing it lacks is cross-device synchronisation to allow me to read from where I left off no matter which device (phone or pad) I pick up. Maybe having the app save its book position/mark index to Google drive (or any similar cloud provider) would do the trick. I'm awarding all five stars anyway, but would love to see a synch feature in a future update.

R70%
by R####:

Highly customizable, every option you could want including advanced font settings, custom touch areas, titlebar with progress meter and/or battery % and clock. Bug with TTS where skipping backward results in voice skipping backward but highlight skipping forward.

Q70%
by Q####:

Unfortunately sentences, even those climactic ones at the end of chapters, were cut off from the second or third word; using another app showed the whole sentence, meaning that this app is faulty in some way. It's a pity, because I liked the look and feel of this app along with the slide screen brightness.

Since Marshmallow, doesn't use ext storage. won't even load from it. "trying to load book from non-standard location". my favourite app just bit the dust in a gory bloody mess.

Love this app, but just got a new phone with Marshmallow and it can't see the SD card. I see reviews reporting this 6 months ago, so not hopeful this will be fixed. I guess it's the end of the road for me. :(

by Q####:

Allowed me to read many books in situations in which I couldn't have. Really practical and easy to use. Cool fact : you can quickly search words you don't understand in the dictionary, so it's perfect for reading in foreign languages!

On my Galaxy Tab A 6 it keeps on crashing. Very annoying while trying to read, especially having to find the page i was on. Needs an update.

by Q####:

It crashes at random on my Galaxy s7 and my Galaxy Tab s2. Other than that of love the app. I've been using it for years now, and it may crash but it hasn't failed me yet.

Q70%
by Q####:

Can't say it's the best, just because after using it for several years on several devices I never wanted to try another app to compare, because this one has everything I need. It's good enough.

B70%
by B####:

Great app but it looks vile. Everything from the icon to the app background is revolting. I won't have it on my desktop as the icon is so dreadful. If the dev sorts out the aesthetics I'd give it 5 stars.

Q70%
by Q####:

Have been using this app for about 2 years now. Never had a problem till I got a new phone. Every time I exit the app, the font size and the brightness are set to default. Really annoying.

Q70%
by Q####:

The problem is with permissions, obviously. It won't even try to access my external SD card. Sad, because this is perfectly doable (some other ebook readers can do it)

M70%
by M####:

Used to be awesome but now the text to speech skips words, sentences, and sometimes even whole paragraphs. Has been getting progressively worse for at least a year on multiple devices.

K70%
by K####:

Very disappointed that the current version of the app doesn't allow full system browsing. My books are on my MicroSD card, and Cool Reader won't go there.

Q70%
by Q####:

I recently purchased Samshung Galaxy Tab S2 and the same got uprgaded to Android 6.0.1 i.e. Marshmallow. After that, this software is not able to read epub and any other files from MicroSD card. These are showing as txt files . So this software has now become useless for me. May be sone future update will fix this, But fo rnow, this is a major problem with this software.

Really pleased with this FREE app thats read every book I've thrown at it. Use it daily. Now's it crashing a lot & returning back to an earlier page, 3 stars untill that's fixed

by Q####:

I love the application! I only would have one wish to make it SUPER perfect. cloud saving for the book. So I can read the book on all my devices and dont need to remember where I left on my phone, when opening it on the tablet. This would be worth a HUGE donation :-)

As a result can't read any existing books. Most of the options of the program are hidden too now. Very bad.

Always used it on my S4 but disappointed with the S7 operation because it cannot find the SD card and there seems to be no answer from the author about a fix. What a pity

Q70%
by Q####:

I get internal or emulated sd internal, but can't file path to actual external sd card. I have current phone and Android os, and moving files another time is not worth it. Looking for a fix out working app, which ever comes first. Having a reader versatile with formats read and other customization is great. This was my default reader. The initial page load is slower than kindle and bookmarks work, but could be refined and a little more visual.

Used to use this exclusively... updated to new tablet and now cannot access files on sd card so had to install moon reader
