Beer Limit Calculator

How many beers in, roughly? Beer Limit Calculator gives you a fast, simple estimate of your blood alcohol level (‰) using the classic Widmark formula — no sign-up, no clutter, just select, calculate, done.

HOW IT WORKS
• Pick your weight and sex
• Tap the beers you've had — small, standard, pint, can or a full Mass, whatever you're drinking
• Set how long ago you started
• Tap Calculate and see your estimated ‰, plus roughly how long until you're back to 0.0‰

BUILT TO BE SIMPLE
• One screen, icon-based, no typing required for the basics
• Advanced options let you fine-tune beer strength (%ABV) and metabolism rate if you want more precision — but they're tucked away, not in your face
• Works in 15 languages, fully offline, no account needed

IMPORTANT — PLEASE READ
Beer Limit Calculator is for entertainment and general awareness only. It uses a simplified formula and cannot know your food intake, medication, health conditions, or true metabolism. It is not medical or legal advice, does not reflect any specific country's legal driving limit, and must never be used to decide whether it's safe or legal to drive. Alcohol affects everyone differently — when in doubt, don't drive.
