PGN viewer and editor, allows setting, recording and viewing chess games, openings, etudes, etc. with analysis and comments.
Does not include chess engine, so it does not play chess.
A short manual can be found at http://solutionsinhand.com/android/ChessPad.html
1. To download games use a file manager like Astro. ChessPad can work with zipped pgn files as well as with unzipped.
2. Opening a large pgn file can be slow. E.g. 3MB (9MB unzipped) http://www.pgnmentor.com/openings/GiuocoPiano.zip file takes about a minute to load.
Note that only one pgn file can be loaded/edited at a time.
Fixed crashes for some Android OS versions
