Shredder, the most successful chess program ever, is now also available for the iPhone. You can play against Shredder, analyze with him and solve chess puzzles. It offers the usual Shredder standard for your pocket.

In addition to the outstanding playing strength of the 12 times computer chess world champion, Shredder is also able to mimic the play of a human chess player with any playing strength. He even deliberately makes typical human mistakes in those levels.

Solve 1000 built in chess puzzles. Shredder keeps track of your performance and offers advice if needed.

You can adjust Shredder’s playing strength from beginner to master level. If you like, Shredder automatically adjusts his strength to yours. He even calculates an Elo rating for you. This is how the playing strength of chess players is typically measured.

During the game a coach is watching your moves and warns you if you are about to make a mistake.

Great, with one caveat


This is a fantastic chess app - probably the best on the App Store. The biggest problem: I'm just really disappointed that you can play only one game at a time. You should be able to play multiple games you can toggle back and forth between. Right now, it's only one game at a time... Which makes it very slow for playing different positions or openings simultaneously. So that makes it a bit annoying to use as a self-teaching app.

Was one of the best, but..No more!


Now Oct 16, 2016. Ver 1.7.1. This app is still very buggy. No cursor knowing placement of text input. Nothing really fixed.
Since iOS 8 came out I am having so many issues with this app!.. It works, but it has this instability sort of. When typing into the fields I cannot see where I am going to type next letter. No blinking of a cursor, nothing! There are other issues like getting hung for a second. It works as a Chess engine, but not as an iOS app. When it will be fixed I will then adjust my review accordingly. I am waiting already too long for an update!

Best chess app for the iPhone


I have Shredder for iPhone and iMac. I recommend both to beginners and expect players alike. Its ability to adapt to your playing strength is unique. It does not make silly moves and blunders. It is packed with useful features as far as the comparisons with other iPhone apps are concerned. The author and developers are responsive. Thanks you for such a great chess program!
