Promilaj

Estimate your blood alcohol level using the Seidl model. Track drinks, monitor countdowns, and stay informed — in 10 languages across 12 countries.

Promilaj is a blood alcohol content (BAC) estimation tool for those who want to track their alcohol consumption and monitor their estimated promille level using the scientifically validated Seidl model. WHAT DOES IT DO? Records the drinks you consume by category and allows you to review your history. Calculates an estimated BAC based on your height, weight, age, and biological sex. Models the absorption, plateau, and elimination phases of each drink individually for more accurate time-based estimates. Displays the legal driving limit of your country as a reference. Shows countdown timers for how long until your estimated BAC drops to the legal limit and to zero. Allows you to create two independent profiles to monitor two people separately. IMPORTANT DISCLAIMER Promilaj provides only an approximate calculation. Your actual blood alcohol level may vary significantly depending on factors such as food intake, medication use, fatigue, and individual metabolism. Do not make any decisions based on the values shown. For accurate measurement, always use a certified breathalyzer and consult authorized medical or legal sources. Promilaj does not encourage alcohol consumption or driving under the influence, and provides no advice on whether it is safe to drive. That decision is entirely your own responsibility.
