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.


- Blunder checking
- Multiple line analysis
- Graphical evaluation of your game
- Game previews
- Dark mode support
- Endgame tablebase
- Opening books

- It's free. Why not just download and try it yourself?

Best engine with extra functions

Update, found bug where when saving a set of four games (pgn) from email. First game is overwritten and inaccessible. Happens without exception.

It is clean and effective.
Btw thanks for the fix of the bug where analysis could be lost by making an alternate move.
I do have a suggestion, currently it locks play (of analysed game). It might be an improvement if it allowed you to explore alternative lines as variations. Most major engines do this. However no pressure, this is an excellent app as stated.

It is great fun

I played the first time and lost. Still enjoyed it though! I really like to see the computer thinking about the next move. Then he suggest moves to me that I’m not sure I agree with. Lighthearted and less serious than the Stockfish app.

Is lovely!

Is a great companion. Sometimes the algo takes too long to make its move even at the fastest settings. Could also offer more choices from for board colours. But all in all a fantastic app!
