Alculator
Know When You Can Drive
A precision BAC calculator that gives you the exact math you need to make informed, responsible decisions. Calculate your blood alcohol content and time until sober.
The Problem
When you ask 'When can I safely drive?' after drinking, AI refuses to answer due to liability. Existing apps give inaccurate single numbers. You deserve data, not lectures.
The Solution
Alculator uses the gold-standard Widmark formula with honest confidence ranges. We show you when you're likely under the limit with a safety buffer. We never say 'safe to drive' - we show you the math.
