Congressman Jim Himes has announced the winners of the Congressional App Challenge, designed to engage students’ creativity and encourage participation in computer  science and coding.  The 4th District winners this year are from Darien High School for an app that was related to health and fitness, allowing users to track their progress towards building healthy habits, such as sleeping more and drinking more water.  A Wilton High School student placed 3rd.  Middle and high school students nationwide compete within their congressional district by creating and exhibiting their software application, or “app,”  for mobile, tablet, or computer devices.
