This summer (or anytime), when your youngsters say "I'm bored", have them check out The Reading Game from LegendApps.
The app itself is not something you read. Rather, the app encourages kids to read their favorite books and come back to the app to mark off how many pages they have read. As milestones are met, rewards (funny sounds, animations, etc.) are unlocked.
The app's custom graphics are beautiful and even though the app is not compiled for the iPad, they render well in the 2X mode.
