What’s New

Version 2.13.0

This app has been updated by Apple to display the Apple Watch app icon.

Fixed a bug that caused the target area for the toolbar buttons to be shifted a few pixels up, making it difficult for some users to hit the buttons reliably.

Fixed broken move lists (not the one below the board, but the one that appears after tapping "Move" and "Move List" -- does anybody use this one?) on the new larger iPhones.

This app is due an update, the last update was made in 2014 with at least 4-5 updates in that year!

I played on a chess app called valil chess and droid fish, valil chess and stockfish kept drawing, where's droid fish and stockfish is 50/50.

I'd love to see komodo 9 on here, can this be possible?

I'd happily pay £40-£50 for it providing there's evidence that komodo 9 can beat stockfish 6 with no trouble.

Please input komodo 9! No developer has done it, why not do it for this app to stand out in so many ways just because of komodo 9!

Kind regards

The best chess engine,

Stockfish is definitely one of the very best chess apps in the App Store. At the time of writing it has the strongest chess engine of any app. Even better it is free!

It is an absolute must for serious players and very worth getting for people who just fancy a game every now and again

While it doesn't offer as many features as some other paid Apps it is easier to use, looks better, and can hammer even the best players in the world. Luckily it comes with easy to play options for the rest of us.

(There seems to be something in the App Store called Chess _64. This seems to be direct rip-off and costs £4.99. Apologies if it is not. However Stockfish itself is so good, if the developers wanted £4 99 for it I would happily pay.)

Too hard

I am not stupid! But I certainly feel it when playing this app. Have had it for years now. Played so much. But I don't feel I get any better. And hardly ever beat the AI, even on its lowest setting. In fact I see very little difference between level 20 and level 1! So I'm going elsewhere to find an easier player that makes an occasional mistake like I do! I play on the tube on way to work so lose concentration a bit. I know that's not the way to play but when you're a chess addict!? Great for chess veterans. Not that great for average players like me. I have no self esteem left
