Alcolater: Promille Alkometer

Alcolater is a simple blood alcohol (BAC) and promille calculator — a digital alkometer that estimates your promille in seconds. Enter what you've had to drink, plus your weight, age and sex, and get an instant estimate of your blood alcohol level using the scientifically recognised Widmark formula — plus an estimate of when you'll be back down to 0.0. Whether you're keeping an eye on your promille at a party, a Friday bar or a dinner, Alcolater helps you understand your alcohol level at a glance — like an alkometer in your pocket. KEY FEATURES - Promille and BAC estimate using the Widmark formula - Digital alkometer: see your promille in seconds - See when your promille is expected to reach 0.0 again - Follow your promille hour by hour - Add your drinks (beer, wine, spirits, shots) and the times you drank them - 7-day history, grouped by day - Works offline — everything stays on your device - No ads, no tracking, no account required Alcolater Pro (optional subscription) unlocks the full experience with a 7-day free trial. IMPORTANT — GUIDANCE ONLY Alcolater is a digital alkometer that gives an estimate of your promille — it is not an approved breathalyser. Your real blood alcohol level depends on many personal factors such as medication, health and metabolism. Never drive after drinking alcohol, no matter what an app shows.
