The Alcoo-sim Be my angel app is a blood alcohol calculator, which you can use for preventive and educational purposes. It provides information on alcohol consumption risks, especially when driving a vehicle. Your blood alcohol concentration is calculated according to your profile (sex and weight) and your consumption of alcoholic beverages. The interactive curve enables you to follow the evolution of blood alcohol concentration over time. The user-friendly interface, paired with existing Smartphones specificities, allows a simple and efficient use. Warning: Results are provided for information purposes only. Legally, only a blood sample prevails. If you are drinking, don’t drive! Be careful: being tired, stressed, under drugs or medication reduces the ability to drive. Be my angel is an alcohol and road safety prevention program, based on the designated sober driver concept, taking his friends back home at the end of the night. Our prevention teams are active in festivals and party scenes to promote this concept. More information on www.bemyangel.ch
