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

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.

One of the best chess apps

Shredder’s user interface may have been overtaken by Christophe Theron’s Chess Pro based on the Chess Tiger engine. Despite its weaker engine, Chess Pro only narrowly wins overall as a better app due to better game analysis functionality that Shredder Chess also has. I would not recommend one over the other but rather getting both!

Some of Shredder’s outstanding features are the simplicity and elegance of the user interface, ability to randomly alter the engine’s personality, automatic Elo rating adaptation based on game outcomes, ability to transmit games individually or as a collection of games in PGN format. Chess Tiger Pro currently cannot email as a collection of games but rather individually.

Despite its age, Shredder remains one the best chess playing apps on iOS. It’s playing strength can automatically be adapted to the user’s playing strength if desired. There is an opening book. There is a basic position analysis function. There are puzzles. There is an indicator about which side is winning during the game. While not as good as a graph, it still makes it easy to detect blunders when there are abrupt shifts of the indicator.

The biggest negative about Shredder is that it’s iPhone version is a separate purchase :-(

Well-done Chess app, BUT...

Shredder's iOS chess version is a well designed app. But the reply to a recent email I sent the company was misleading. Importing outside games was not added to this recent update. It still cannot show a move list which would allow you to quickly return to an earlier point to attempt a different move sequence. As a result, reviewing a game in Shredder is more cumbersome than Stockfish, tChess, Hiarcs, and ChessHD. The full-computer version of Shredder was just updated to v13 from v12 so I assume this app is stronger? The game's analysis function is nice but less useful than those of the tChess and "Analyze This" chess apps. It is hard to evaluate playing strength between the top iOS chess apps but Stockfish almost certainly is the strongest, and it may get an update soon as the full-computer version went from v7 to v8 a few weeks ago. Important - Stockfish is FREE.

Shredder's value is its interface - the Puzzle Section is fun but a more extensive iOS "chess puzzle only" app is available and less expensive. The game play interface is easy to use(!) and attractive, and I enjoy the "game evaluation meter" over a simple number for whom is ahead in a game as seen in the other chess apps. Lastly, it is still possible that more database and game importing features will be added if the firm's recent email to me was accurate.

I like Shredder and I do have hope.

Good app; could use a few refinements

I really like this chess app. It's very strong, has a nice rating system, when you set it for lower levels, it degrades play in a more realistic fashion than many chess games. It's a great app.

Having said that, there are still curious oddities.

* For example, the “new game;setup position; enter moves; start analysis” menu is using the “export” icon. That makes no sense to me. The iOS app uses the “+” icon, which while not perfect, seems closer. I’m not sure why the iPad and iPhone apps use different icons.

* I wish it had cut/paste and import/export features to get PGN/FEN representations in and out of the app.

* I wish the game database could (optionally) be shared between devices. Perhaps put it in iCloud?

* I wish the iPad game supported multitasking (both split-view and slide-over), allowing me to read a chess book and analyze a game at the same time.

* I wish the app supported annotations, tappable move list, etc. At the very least, given all of this iPad screen real-estate, show us more than two moves in the list at a time!

But I still love this app. I think it's the best chess app out there. But it’s not keeping up with device capabilities introduced over the last few years...
