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.
