Really enjoying the spare interface.
Fast positional-thinking. The only thing I’d add is a legend to explain the various symbols (+ - <>), accessible from one of the pull-down menus (no need to clutter the wonderfully spare interface).
Typical for game apps on the App store. A basic engine that crashes often and has no functionality. If all you need is stripped down chess engine with absolutely no bells or whistles, I guess you will be happy with this app. But I am used to running many high end 64 bit engines on multi-core liquid cooled overclocked CPU’s on Windows machines, so my expectations are a little different. Mac OS is great for some things, just not chess (or virtually any other game).
Stockfish is the most powerful free chess-playing software. That’s the good news. The bad news is that on my iPad it routinely crashes and doesn’t allow you to annotate your games or to save analyses. That said, I use it to quickly check the solutions to chess puzzles and to play a quick game.
With Family Sharing set up, up to six family members can use this app.
