SmallFish is an open source project based on the Stockfish chess engine. It uses the latest Stockfish chess engine (Stockfish 9), 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
- It's free. Why not just download and try it yourself?

Best Chess App In Store

Worth waiting for, tremendous playing strength and very we'll presented with all features that you need, looks nice, plays fast and smooth game play, not to mention it's upgraded to stockfish engine 4.0 and made for the iPad, look no further this is the best chess app in the apple store. Definitely 5 stars all the way. Great work Ted Wong keep it going.

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.
