What Chess App Do You Currently Have in Your iPhone?

With over 350,000 apps in the Apple iTunes Store, there has got to be some for chess playing iPhone users.

Here's my list of the chess App you'll see in my iPhone:

• Chess.com - of course, for playing correspondence chess;
• Stockfish - nothing beats the free but strong chess playing software. There are lots of features missing, though, as compared to the paid apps, but the quality or the playing strength of the engine is something you shouldn't even let pass;
• tChess Pro - I opted for this one over Shredder Chess and Hiarcs because of the compatibility of the one app for both iPhone/iPod Touch and the iPad, meaning once you purchase one for iPhone, you don't have to repurchase another version for the iPad. Plus, I really liked how you can open PGN files from your email to this program, quite handy if you need a quick analysis of any game you have at your disposal;
• Online Chess - used this to play chess at FICS (freechess.org), but because of the too small interface for rapid and especially blitz games, this isn't just the optimal software and hardware;
• ChessClock - a free app that you can use as a digital chess clock. Quite handy especially if you mind lagging around with your official chess clock. With this app, you always have a chess clock (and digital that is, you can play fischer time with increments, etc.) at your pocket;

What about in my iPad? That's for another post. What about yours? What do you have in your iPhone/iPod Touch/iPad so far related to chess?
