The Web-based application Nudge ( nudgeyourself.com ) allows users to log their eating and exercise habits — and to score points for good behavior. Marketed primarily to business owners and human resource managers, the app is designed to inspire healthy lifestyles among a company's workforce, controlling health care costs and boosting productivity. The health-based technology was developed by Richmonder Mac Gambill, who collaborated with college friend Phil Beene of Chattanooga, Tenn., and Chris Garson of Northern Virginia, and is in use at several local businesses.
