AlcoInsights is a science-based blood alcohol content (BAC) tracking application built by KinnmanAI in Sweden. Our methodology is grounded in established pharmacokinetic research and peer-reviewed science. BAC Estimation: We use the Widmark formula, developed by Swedish chemist Erik Widmark in 1932 and still the standard in forensic toxicology worldwide. Our implementation includes gender-specific distribution ratios (r-factors), customizable elimination rates from 0.10 to 0.20‰/hr, a 30-minute absorption window with 10% instant absorption modeling, and optional BAC calibration using personal breathalyzer readings to refine individual parameters. Hangover Risk Scoring: Our proprietary hangover risk algorithm uses a weighted scoring system based on published risk factors: total alcohol amount (35% weight), peak BAC reached (23%), time spent above elevated BAC thresholds (14%), drink type mixing (10%), high-ABV beverage consumption (10%), and drinking pace (8%). Hydration tracking can reduce the score by up to 20%, reflecting research showing that water consumption during drinking sessions reduces hangover severity. Goal System: AlcoInsights supports evidence-based goal types aligned with WHO and NIAAA guidelines — weekly unit limits, per-session maximums, drink-free day targets, calorie budgets, and graduated reduction goals. Research shows that self-monitoring reduces alcohol consumption by 20–30% (Garnett et al., 2019). Regional Guidelines: We incorporate drinking guidelines from 7 countries (Sweden, UK, USA, Canada, Australia, Denmark, France), each with different definitions of a "standard drink" and recommended weekly limits. Privacy: All personal data is encrypted and stored securely. We never sell user data or share it with third parties.
