The Stay in the Blue app aims to help students (and other community members) keep their drinking at lower risk levels. The Stay in the Blue campaign encourages those who drink to stay at a .06 BAC (blood alcohol content) or below, and non-drinkers are always in the blue. It includes standard size drink options available at establishments or private events. This also encourages mindful measurement of standard drinks. It allows individuals to track their BAC in real time or get a snapshot by planning ahead, provides prevention strategies, alerts them at .08 BAC (legally drunk level) or above, has University of Michigan policy information, lower risk drinking tips, and transportation options. At the end of a drinking session, it gives a total number of standard drinks, showing app users if they are in the blue (preferred), maize, orange, or red. It will also allow them to save these sessions so they can have a visual representation of how they are doing over time. The same data can be saved from the "plan ahead" feature.
