Uncharacteristically, non-game apps top both the iPhone and iPad top grossing app charts this week. On the iPhone, Major League Baseball’s MLB At Bat takes the top spot for the second week in a row. On the iPad, TurboTax 2011 Tax Preparation vaults to the No. 1 position as the U.S. tax deadline looms.
By far the week’s biggest gainer is Storm8’s iMobsters, which climbs an impressive 80 positions to rise to No. 10 on the top grossing iPhone charts. The free-to-play mafia-themed game has been surging up and down the top grossing charts for the past month, but has not been updated since Jan. 19.
