Alcohol calculator

Alcohol Calculator (Breathalyzer) - Track your Blood Alcohol Content (BAC) and Sobriety Level based on the internationally recognized Widmark formula. Simply input the amount of alcohol consumed and let the app calculate your BAC and level of intoxication.

New: Live Mode — start a session and track your BAC in real time as you drink. The app continuously updates your current BAC, shows a chart of how it changes over time, and estimates when you'll be completely sober.

Stay safe and responsible while having a good time.
