Abstract: A system and application for maintaining and tracking accountability by users. The system allows a user to create and assign one or more tasks, actions, or objectives to one or more other users, receive information or confirmation from said one or more other users of a status or completion of a particular task, action, or objective, and respond thereto, if necessary. In several embodiments, two or more users may jointly send and/or receive information or confirmation about the status or completion of a particular task, action or objective, thereby providing accountability among the group of users. The particular task, action or objective may be assigned, performed or accomplished by a single individual, by members of a group individually, and/or by members of group together.
