Original Stockfish for iPad (Free, open source):
iTunes link: http://itunes.apple.com/us/app/stockfis ... 58605?mt=8#
Cờ VuaBy NHAN NGUYEN HUU ($1.99):
Not a single reference to Stockfish, either in the application, either in its iTunes description. By this screenshot one can see that Mr. Nhan Nguyen Huu can change a string in a source but can't play chess ^^

Deep Fish ChessBy ElementoApps Enterprise ($.99):
Slight cosmetical changes, with the mention "powered by Stockfish engine".

Chess(Special Version)By Tran Van Luong ($1.99):
Yes, he managed to make it awful. I have no idea why this version would be "special", because I didn't want to spend $1.99 for it when Stockfish is free. Maybe because it's broken? Doesn't seem to be any mention of Stockfish anywhere, and the description just says:
The "author" doesn't even seem to be able to play chess either, if one will judge by this screenshot.************************
HAVE FUN !

This is just for this week, there are numerous other clones of Stockfish in the AppStore, nearly NONE of them being free. This is a real plague. As I kind of collect all of the chess applications I've been deceived a few times by other kind of apps: those that use stockfish with a different enough interface to lure us into buying them. I think StockFish's team should do something about that.
