Trash

Don’t waste money. I regret buying this. Interface is horrible in the first place. There is no accuracy indicator, and not very helpful in analysis. Chessigma is free and far better than this.

★★★★★Feb 27, 2026
Best chess app!

I tried several chess apps to let me record, play over and analyse games, my own and others, before lighting on Smallfish. At last I had found one that did everything I wanted, in a clear and elegant interface, and with the bonus of the wonderful Stockfish engine in the background. I cannot imagine a better conceived and executed app for chess game storing and study.

★★★★★Mar 28, 2025
First class app

And the best in the store now that I cannot find “Stock fish” nor “Analyze This”. Useful for playing over games, opening PGN files and examining FEN positions. Excellent interface, look and feel. Very strongly recommend.

★★★★★Jan 26, 2025
Thanks!

This is a great app, free and full featured. I really appreciate the help from the stockfish engine e and it’s made my life learning how to pay and understanding moves and openings much easier. Thank you all team! Ps. Hopefully this is constructive feedback - the UX around the menus could use some work, it’s hard to know what is where and how to move between screens and buttons appear and disappear or change function when your on one screen or another.

The Rolls Royce of Chess Engine Apps

A brilliantly beautiful app. Good things do come in small packages 👀

Chess monotony
