SmallFish is a project based on the Stockfish chess engine. It uses the latest Stockfish chess engine (Stockfish 14 NNUE), rated about Elo 3300+ and is one of the strongest chess apps.

The app derives from the SmallChess app (another top chess app) to create stunning chess playing experience for absolutely no cost! The strongest chess app is free, something very hard to believe but it's true.

SmallFish offers you three distinct ways to improve your game. You can review your game with comments, or study how Stockfish thinks, or track your progress.

SmallFish is simply amazing.

Its free, but ....

It seems to only offer a limited number of moves when starting new game? Aftaer half a dozen or so moves, just stalls. Am i missing a paid version i cannot see? Or just another bug?

Epic sudoku ,

Excellent but crashes far too much

By far it is the best chess app I have ever used, however it is pretty unstable and crashes and freezes far too much.

Developer Response ,

Understandable. I'm working on it.
