Every week, GameSetWatch rounds up the top-grossing iPhone, iPod Touch and iPad applications, as current that day in the iTunes App Store. This week's U.S. revenue charts see Zombie Gunship and Texas Poker earning top iPhone sales, while Smurfs' Village and Sid Meier's Pirates! emerge as big sellers on the iPad.

These charts allow end users to see who is making the most money on the App Store that day. It differs significantly from the Top 10 Games chart, which is ranked by sales, and therefore is dominated by lower-priced titles that sell more copies.
