Still the king...

A lot of chess apps have come along since Chess Genius came out, but its still at the top of the pile. The interface is simple, usable, elegant - and the integration of analysis and naming openings is the best there is. (My one request/wish would be some indication of when you go "out of book" without having to turn on full analysis, but thats a relatively small beef.) This is still the only app that lets you import PGN game files/databases from a URL (all you need is a free Dropbox or Syncplicity account, for instance), so you can take your favourite grandmaster games or openings repetoire with you wherever you go. FANTASTIC!
