Rage of Bahamut, The Simpsons, Textbooks and more on this week’s top grossing iOS app charts

DeNA’s Rage of Bahamut reclaimed the No. 1 spot on the top grossing apps on iPhone chart, dethroning Kabam’s social city building Sim Kingdoms of Camelot: Battle for the North which dropped to the No. 3 spot.

Back to school season has been kind to Kno’s Textbooks app which comes is at the No. 18 spot on the iPad chart. The app allows K-12 and college students to replace their physical textbooks with digital copies they can read on their iPads. It also includes note-taking tools, Dropbox integration and other interactive features possible only on a tablet device. Textbooks is free to download with in-app purchases.

Another notable gainer this week Electronic Arts’ The Simpsons: Tapped Out, a city-building game based on the beloved animated series. The game was first released back in March but was removed from the Apple App Store shortly thereafter due to connectivity issues. Now, with the issues presumably addressed, it comes in at the No. 6 spot on iPhone and the No. 9 spot on iPad.
