22 Best E-Book Reader Apps for Android & iOS

Paper books are becoming obsolete, although they are still a popular way to get information or have a good time.

But they have a few disadvantages: firstly, their creation takes a huge amount of paper and resources, which are running out so rapidly, and secondly, if you do not live in a large city, it can be difficult to find a copy of the publication you are interested in. Therefore, eBooks are gaining popularity – a more practical and convenient option.

But without the presence of the device for reading will be difficult to familiarize with the book and its contents. You can convert your smartphone into a real e-book reader by simply downloading the appropriate application. We have gathered for you in one article 22 best e-book readers for iOS and Android.

And before you start, for all those who love to read we also offer to check out the article about the best book club apps & websites to create book clubs.

Amazon Kindle

Amazon Kindle is considered to be a real online bookstore, where everyone can find something suitable for them. This application helps you to manage the market, keep track of the latest novelties and even the prices of literature – you just need to use your account and save your favorite books.

Amazon Kindle offers you the most competitive prices in the eBook market. The most important thing is that in this huge library there are not only classical works, but also the latest hits and bestsellers. Content on Amazon is created by the authors themselves, so that the reader will have access to modern literature and can go beyond traditional writers.

The application itself is easy to use, but there is some problem with buying books. To buy the edition and upload to your account, you will need to switch from the application to a browser.

Otherwise, text management works fine: you can customize the font color and style, its size, line spacing and other details that make your reading more comfortable.
