BAC Calculator – Breathalyzer

BAC Calculator – Breathalyzer helps you estimate your blood alcohol concentration (BAC), track drinks during a session, and see how your estimated BAC changes over time.

Use the app as a practical alcohol calculator and BAC tracker when you want a clear overview of your drinking session. Add drinks as you go, review your estimated BAC on charts, check your session history, and see an estimated time until your BAC returns to 0.00%.

TRACK YOUR BAC OVER TIME

Instead of showing only a single result, the app lets you follow your estimated blood alcohol level throughout the entire session. Each recorded drink is added to the calculation, while the chart shows how your estimated BAC rises and falls over time.

ESTIMATE WHEN YOU MAY REACH 0.00% BAC

The sober time estimate gives you an approximate indication of when your calculated BAC may return to zero. This makes it easier to understand how long alcohol can remain in the body after drinking has stopped.

REVIEW YOUR DRINKING HISTORY

Completed sessions can be reviewed later using the history, calendar and statistics tools. See previous BAC estimates, peak values, drinks and session timing in one place.

BUILT FOR PRACTICAL TRACKING

Choose your drinks, enter your personal parameters and let the app calculate an estimated BAC throughout the session. The interface is designed to keep the most important information visible without unnecessary steps.

IMPORTANT

BAC results are estimates only. Actual blood alcohol concentration can vary significantly depending on metabolism, health, food intake, medications, drink strength and many other factors.

This app is not a medical device or a real breathalyzer and does not measure alcohol directly. Never use an estimated BAC result to decide whether it is safe or legal to drive, operate machinery or perform any activity that requires full sobriety. If you have consumed alcohol, use a reliable certified measurement method and follow local laws.
