A system includes memory for storing a list of contacts, the memory integrated into a smart device; and a locking application configured to permit a user to select and lock one or more contacts included within said list of contacts such that the user is unable to communicate with the selected one or more contacts via said smart device. The locking application may be further configured to permit a user to select a pre-established time period during which the one or more selected contacts remain locked. Challenges may be presented to the user to unlock the contacts in advance of the lockout time expiring. Optional features include GPS tracking, rewards, ride and networking modules.
