Blood Alcohol Calculator is a free Android app developed by FVBAgency under the Lifestyle category. The app helps users calculate their blood alcohol content (BAC) using the formula of Swedish scientist Erik Widmark.

The interface is user-friendly and straightforward. To calculate BAC, users need to enter the volume of the drink, the alcohol content, and the time of drinking. The app then calculates the estimated BAC. However, it is important to note that the Blood Alcohol Calculator is only intended for estimating blood alcohol content and should not be used to determine whether it is safe to drive or for any official form of blood alcohol measurement. The app does not replace the official breathalyzer test and should not be used as such.

Overall, Blood Alcohol Calculator is a convenient app for those who want to estimate their BAC quickly. It is easy to use and provides accurate results based on the input.
