Computer Chess Royalty!!!! Unfairly criticized on here. Great gui. Easy to use and work with. Great features. Love the tatical puzzles. You could download this app and never need to use another program. It has everything you could ever want. If you wack it up to 2600 elo and play 1 minute chess you can win on time with anti computer tactics and the engines horizon effect. However go to settings and click option for full strength and you will see why Shredder is the undisputed king of speed chess. A super GM in you hand. Enjoy
Promising, but appears to be abandoned This could easily be the best Android chess app, but at present it needs polishing. The UI desperately needs to be overhauled and modernised, and many needed features should be added. Examples include auto-save, fine-grained time controls and pause clocks option, full move list in game with random access, and extra info like the opening name/code, more detailed statistics, etc. Full game analysis would also be great.
Finally, the chess app feature this casual player was looking for It's missing the option to start as a random color, but the self-adjusting difficulty more than makes up for that. The most annoying thing about other chess apps for me was trying to tweak the difficulty to keep at a 50-50 win rate.
The best mobile computer chess game I have ever played against. Most top out at around 1800 - 2000, but this one is still whooping butt at that level. I actually have it around 2250 and win only half the time. Definitely worth the time to play
Chess Study Tool and Workout Strong engine. Good features. Inexpensive. Don't waste your time on free crap. You'll get a weak engine, few features and obnoxious ads. They are little more than Trojan horses to sell you violent video games. This is a good choice for someone looking for a serious and effective chess improvement tool.
Excellent puzzles The engine is uncannily quick. The app starts up immediately, works offline, and the tactics section is a goldmine of puzzles, which you can not only solve, but play against the computer. The setup position feature, though, is very clumsy. It's impossible to tell whether you're setting up a board facing white or black (it changes based on recent activity). Otherwise, a great app.
