AlcoTrack is a blood alcohol content (BAC) calculator, alcohol consumption tracker, and drinking diary, all rolled into one. It can give you an estimate of your current blood alcohol level based on self-reports of your alcohol consumption. Optionally, it allows you to track the costs and calories of your drinks and gives you an overall impression of your drinking habit. It also acts as a sober day counter, providing you with challenges to motivate you to establish a healthier drinking behavior.

Featured on xda-developers.com as recommended alcohol tracking tool for New Year’s Eve.

DISCLAIMER
AlcoTrack: BAC Calculator & Alcohol Tracker is a drinking diary app to track your alcohol consumption, analyze your drinking behavior, and, ultimately, estimate your blood alcohol content (BAC). Please note that since your BAC is depending on many individual factors, this app can only give you a rough orientation. AlcoTrack cannot replace a breathalyzer or any other proper alcohol/drunk test. In case of doubt, you should never drink and drive! I do not assume any liability for the correctness of the results.

Formerly known as AlcDroid.
