Happier.com (http://www.happier.com) — a web site created to help
users measure, track and improve their level of happiness —
released a mobile application for the iPhone. Users of happier.com’s
“gratitude journal” are directed to make a daily entry of three
positive events that happen each day.

A 24-question assessment then informs the user of their happiness
score. Users can track milestones and increase their happiness over
time using the gratitude journal. The new mobile application includes
an introduction by “happiness expert” and University of Pennsylvania
professor, Dr. Martin Seligman.
