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. You can also control the internal engine parameters.

The interface is an example of a "flatten" design - dropping of heavy textures and the addition of several new simple user interface elements.

SmallFish is simply amazing.


- Blunder checking
- Multiple line analysis

Ok, but could be streamlined

I really want to like this app, and keep downloading it when a new version is released. I keep going back to the official Stockfish app though, as it offers a better playing experience and looks better IMO (on iPhone). Smallfish is better for analysis, but I tend not to do that on my phone.
