Merry Miser

Merry Miser is a mobile application which persuades people to spend less money, and think more about their spending. By combining users' real financial transaction information, their location, and personal assessments of spending, the application presents deeply personalized and compelling interventions at the time and place when they are near an opportunity to shop. The interventions help to reinforce choices that are in the users' better long-term self interest, against short-term impulses.
