Alcohol Tracker

Alcohol Tracker estimates your blood alcohol content (BAC) in real time and helps you stay in control of your night. Simple, fun and 100% private: everything stays on your phone.

YOUR BAC, LIVE

Add your drinks in seconds and watch your estimated level evolve minute by minute: rise, peak, decline and the estimated time until you're back to zero. The estimate is based on the scientifically recognized Widmark formula and your profile (sex, weight, age, height, meals).

40+ READY-TO-USE DRINKS

Beer, wine, cocktails, shots… pick from the illustrated catalog or create your own drinks. Log what you've eaten (snack, meal, large meal) to refine the estimate.

YOUR NIGHT ON A CURVE

See your whole night on a clear curve: where you are, where you're heading, and when your estimated level should drop back under your country's legal limit.

TIPS THAT LOOK OUT FOR YOU

Drink water, grab a bite, slow down: the app nudges you with the right reflexes at the right time — and will never tell you it's OK to drive.

YOUR STATS, YOUR HISTORY

Look back on past nights: drinks, alcohol units, spending, alcohol-free days, records… everything you need to keep perspective on your consumption, week after week.

GUEST MODE (VIP)

Need an estimate for a friend? Add guests with their own profile and switch between people in one tap.

100% PRIVATE

No account, no sign-up: all your data stays on your device and you can erase everything at any time from Settings.

IMPORTANT — PLEASE READ

• Alcohol Tracker provides an estimate for information only. Your real BAC depends on many individual factors: the app is no substitute for a certified breathalyser or medical advice.

• The app will NEVER tell you that you are fit to drive. If you've been drinking, don't drive.

• For adults only (18+). Excessive drinking is dangerous for your health; please drink responsibly.

VIP (optional): ad-free, full statistics, night cost tracking, guest mode, home-screen widget and unlimited custom drinks. Monthly or yearly subscription (7-day free trial on the yearly plan), cancel anytime from Google Play.
