Emerging top grossing iOS apps: Monster Galaxy, Action Movie FX and Run Roo Run

This week’s iOS top grossing charts showed a little more variety than we’ve seen in previous weeks, although new releases were still scarce. Between old favorites battling for top spots on both the iPhone and the iPad charts, 5th Cell’s new game Run Roo Run makes a strong showing thanks to a large push from Apple, which selected the game as its iPhone and iPad game of the week.
