Staying in the Blue can help you get what you want while avoiding the stuff you don't want, by keeping your blood alcohol content (BAC) at .06 or below. 

Our free app can help you Stay in the Blue and features: 

  • BAC Calculator: Enter gender* and weight, then choose type and number of drinks over time. The app calculates and displays estimated blood alcohol content; the recommended  Blue (.06 or below, safer zone), or more risky zones of Maize, Orange or Red. (*For transgender people who are not taking hormones, use your sex assigned at birth when setting up the app. If you are taking hormones, use the sex consistent with those hormones for the most accurate BAC estimate.)
  • Call-a-Cab: Calling local cabs is just a click away—you even get your GPS location.
  • Tracker: Tracks drinking events over time if you want to see how often you are staying in the blue or in other zones.
  • Events: Displays a list of fun things to do in Ann Arbor.

Use your iPhone or Android smartphone to download the app from iTunes or Googleplay. Upgrades coming fall 2015!

Don't have a smartphone? Then check out the BAC Calculator (downloads an Excel File) to help you plan your party.

It really works! 

Many Michigan students have figured out that moderating alcohol intake means more fun, less drama, and they're happy to share their success. See How U-M Students Stay in the Blue.

How many standard drinks in that?

Take the Alcohol Serving Size Challenge.

What's a drink? Drinks contain differing amounts of alcohol, so before you can estimate your BAC, you need to know what a “standard” drink is. One "standard" drink is equal to .6 oz of ethanol, so:

  • 12 oz beer or wine cooler
  • 1 oz liquor (100 proof) or 1.5 oz liquor (80 proof)
  • 8-9 oz malt liquor
  • 5 oz table wine
  • 3-4 oz fortified wine (sherry, port)
  • 2 oz liqueur, cordial, aperitif
  • 1.5 oz brandy

Did you know that red party cups contain 16-18 oz and 1.33-1.5 beers?  Mystery mixes in Igloo coolers or Gatorade jugs often contain 3-6 drinks per red cup, but who knows for sure? Long Island Iced Teas at local bars typically contain 4-5 standard drinks.

Individual effects:

Alcohol also affects individuals differently, and BAC may be affected by your:

  • Gender
  • Emotional state
  • Physical condition
  • Hydration status
  • Amount of food consumed
  • Menstrual cycle
  • Any additional drugs or medication

Don't forget your EANAB!  (Equally Attractive Non-Alcoholic Beverage) The more you make them available, the safer your party can be!
