Public voting for the best app closed on August 14, and after Obama and a panel of experts combed through a hundred submissions, they selected Zisboombah.com as the winner -- and recipient of the hefty check.
The website, launched by Karen Laszlo last November, encourages kids to build their own healthy meals through activities and games. Once they do, that meal is sent by e-mail to the parents, who can use it to reward healthy choices.
Now that the company has come into a little more cash, it plans to expand the activities on the website and launch a nutrition-education curriculum to be used in elementary schools.
"It has been a wild ride," says Brandon Saranik, who works in marketing at Zisboombah.com. "But we're not stopping here."
