The Apps for Healthy Kids competition is part of First Lady Michelle Obama’s Let’s Move campaign to end childhood obesity within a generation. The competition challenges software developers, game designers, students and other innovators to develop fun and engaging software tools and games to urge children, especially “tweens” (children ages 9-12) – directly or through their parents – to eat better and be more physically active. The applications are software tools or games for the web, personal computer, mobile handheld device, console or any software platform available to the public. USDA Photo 10di1506--28 by Bob Nichols.
