DroidFish Chess

DroidFish is a feature-rich graphical chess user interface, combined with the very strong Stockfish chess engine.

DroidFish is primarily designed for engine analysis of chess positions and viewing and editing of chess games. It can also be used for playing games, either against a chess engine or against another human player. Both players must play on the same device though.

A much weaker chess engine called CuckooChess is also included in DroidFish. Its primary feature is that it can be made to play very weakly so that even beginners have a reasonable chance to beat it.
