Comments on Cool Reader for Android

★★★★★ The most amazing app for book reading. I have been using that app more than 10 years. Stable and works always perfect.

★★★★★ The best book reader ever! I've been using it for several years on defferent devices. Just perfect. Thank you.

★★☆☆☆ This app used to be great 6–7 years ago. Just when I thought it couldn't get worse. It no longer follows the text when reading aloud. Before you were able to double tap anywhere, and it would read the text. Why do they take a working product and make it worse? The latest installation causes the page to turn, painfully slowly when you try click for the menu option, it turns the page at a snail pace speed instead. It's definitely a glitch. Making it frustrating to use.

★★☆☆☆ Thanks for your application. The new version is getting worse. I can't manage with the settings. I can't hide the settings panel except the full mode view. But in the full mode there's no any settings panel to use. Also, it is impossible to change a book. It is very hard. Sorry, your app's lost the scores for me. There's a problem with a brightness, which is changed every time you continue reading, that is independently of the phone brightness settings. Could you correct this?
