Chess Book Study Free is an Android app developed by MyChessApps.com that allows you to read your PDF chess books and magazines while following the games on a chess board, all on one screen. This app provides an excellent solution for chess enthusiasts who want to study chess books and magazines on their phone or tablet.

The app is ideal for large-screen phones and tablets and comes packed with features like the built-in store with magazines from Chessdom, open e-magazines from New in Chess, USCF, Chess Today, British Chess Magazine, and more. You can also analyze with the power of two chess engines, open websites like chesscafe.com and chessbase.com, and even talk to move (experimental).

The app also has book options like day/night mode, bookmarks, multi-touch zoom, crop, split, and much more. It is available for free with ads, but the free version does not have the save game option and has other minor UI limitations while loading games from PGN.
