Stay in the Blue is a free iPhone app developed by The University of Michigan, designed to assist users in maintaining their alcohol consumption at lower risk levels. The app features various popular alcohol drinks among UM students and at frequented bars, enabling users to monitor their Blood Alcohol Concentration (BAC). It offers safety tips, alerts users when they reach or exceed the legally drunk level of .08 BAC, provides UM policy details, lower risk drinking suggestions, and contact numbers for cab services with GPS location sharing. Additionally, the app calculates the number of standard drinks consumed, categorizes users' alcohol intake as blue (preferred), maize, orange, or red, and allows for saving events to track progress over time.
