Most comfortable reading app – KyBook - EPub,FB2,PDF,DjVu Reader Review

This is the reading app I'm most comfortable with. It supports different formats such as pdf, djvu, epub, etc. And there are many features you can customize such as size and background color. It does everything one needs in a reading app without gimmicks. I highly recommend it.
