Brief Summary
This study will be a three-arm randomized, controlled trial that the investigators will run in 2014 with approximately 4,000 users of an app called Achievemint. AchieveMint rewards users with points (which can be redeemed for prizes) for every step they take. The investigators will be testing three different point-based programs designed to encourage users to build exercise habits over the course of a month: stable incentives, increasing incentives, and decreasing incentives. After the investigators' month-long intervention period, the investigators will observe users' step counts during a month-long follow-up period to test which of the investigators' habit-building programs leaves users with the best exercise habits (or the highest step counts) after they conclude. The time frame of observation will be 8 months.

Outcome Measures
Primary Outcomes (1)
Steps walked
Subjects will track steps walked with pedometers. The investigators will track how many steps they take for 8 months
8 months
Study Arms (4)
Increasing incentives
EXPERIMENTALThe investigators will offer incentives to users that begin low, and get higher over time.
Decreasing incentives
EXPERIMENTALThe investigators will offer incentives to users that start high, and decrease over time.
Stable incentives
EXPERIMENTALThe investigators will offer incentives that stay stable over time.
Usual care control
NO INTERVENTIONThe investigators will offer incentives that are identical to the incentives normally offered by the investigators' partner company.
Interventions
offer incentives that are stable over time, but higher than usual care
