Abstract: A method and system for keeping and tracking group behavior is disclosed. The system may provide notifications to users via mobile devices throughout the day prompting the users to engage in certain behaviors, such as performing a certain exercise or implementing a new food choice. The notification messages may be chosen depending on the group that the user belongs to. Upon completion of the action prompted by the notification, users of the group may reply to the notification indicating that they have completed the action. The responses may be tracked by the system for the purposes of reporting feedback to and providing for accountability for users and administrators of the system. The notifications may be designed to prompt behavior or actions that are brief, so that they may be completed during the course of the day.
