Reading books on small screens is not always very easy, which is where the Marvin app helps out. The app allows you to change the size, font, color and layout of books you are reading, to suit everyone’s different reading preferences. Although there are books which come free with the app, most downloads from their store cost more money than if purchased from other sources, which should be noted. You can also synch Marvin to Dropbox to access books you store there.
