SmallFish is a project based on the Stockfish chess engine. It uses the latest Stockfish chess engine (Stockfish 15 NNUE), rated about Elo 3300+ and is one of the strongest chess apps.

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.

New additions?

Could you please add personality, adjustable search depth, and more evaluation lines (10)! This app is literally the best out there but these are all features I have desperately wanted in one app but haven’t been able to find in an all in one package. Thank you for all your hard work! This app already is the best, but these features would blow the competition out of the water.

Well designed app - update

After updating to ios13.6, it seems that there are graphic issues (piece alignment to the board, coordinates alignment to the board). None of these are impediments to using it, but are annoying.
Please update!
*Having tried many chess apps, I consider this app to be excellent! Most chess enthusiasts say that the only decent chess games were developed for PC. Until finding this app I thought that was true. My preferred choice has been Chess Master- Grandmaster edition (pc version), which I used for more than 10 years. This app is certainly the best contender yet!

Opponent always runs out of time.

No matter what I do in the options, I always win because my opponent runs out of time. The game continues, however, even though the clock is 0.00 so that’s a good thing. This issue starts immediately: playing white pieces, I play 1. d4, black always immediately plays either d5 or f6; I play 2. c4 . . . . black “thinks” 20-40 seconds before making a second move, usually c5. Really? As long as 40 seconds to make the second move. And that “thinking” exists throughout the game. For instance, black offers a queen trade: I accept. Then black deliberates 20, 30, etc. seconds whether or not to capture my queen when there is obvious nothing to deliberate. Hardly a realistic or enjoyable scenario.
