Psychological well-being is the focus of the Happy Fuel app, which encourages users to consider “living in the happy.” The app began as a mobile place to store, gauge, and share the
things that fuel their happy, whether it’s a song, photo, video, place, sound, or thought. It has grown to include a Web app, happyfuel.me, where users can build their own “happy
wall” -- a personal place to share the things that make them happy, and view the same from their Happy Fuel friends.
