About

Drive Sober

Features
Read full description

Drive Sober is a BAC calculator and alcohol tracker that helps you estimate when your blood alcohol concentration may fall below your selected driving limit. Free to use — no subscriptions or hidden fees. Small ads help support development and keep the app free. Choose your country, log drinks in seconds, and follow a clear estimated timeline showing how your BAC may rise, peak, and fall over time. If you're wondering when you may be below the legal BAC limit after drinking — including the next morning — Drive Sober gives you a cautious estimate, not permission to drive. IMPORTANT This app provides estimates only and must never be relied upon to decide whether you are legally or medically fit to drive. If you have been drinking, the safest option is not to drive. FEATURES Estimated BAC Timeline • Visual blood alcohol timeline • Estimated rise and reduction over time • Selected driving-limit line • Red, amber, and green risk zones • Key estimated times • Clear countdowns as your estimate changes Quick Drink Logging • Add common drinks in seconds • Beer, lager, and cider • Wine and sparkling wine • Spirits • Cocktails and mixed drinks • Food and meals • Save favorite and custom drinks for faster logging Apple Watch & Siri • Apple Watch support • Siri support for quicker access to supported actions Live Activities & Alerts • Follow key countdown information from the Lock Screen • Dynamic Island support on compatible iPhones • Optional smart notifications and alerts Detailed Alcohol Estimate See how the estimate changes over time, including: • Estimated BAC • Alcohol absorbed • Alcohol processed • Net change • Drinks added in each period • Current risk status Safety-First Calculations • Conservative assumptions • Upper drink strength used for ranges • Food slows absorption timing rather than reducing alcohol • Designed to avoid false reassurance Profiles & Multiple People • Optional personal profile setup • Gender and build selection • Advanced profile options • Track more than one person • Country-specific driving limits Country & Regional Driving Limits Includes support for: • United States (general reference — state laws can vary) • UK, including Scotland's lower limit • Europe / EEA • Switzerland • Norway • Canada • New Zealand • South Africa • Japan • Hong Kong DESIGNED FOR REAL LIFE • Fast to use • Native iOS design • iPhone and iPad support • Apple Watch support • Dark Mode support • Clear, detailed estimates • Safety-first approach IMPORTANT DISCLAIMER Drive Sober provides estimates only. It is not a breathalyzer and cannot determine legal or medical fitness to drive. Alcohol affects people differently, and no app can tell you that it is safe to drive. If you have been drinking, the safest option is not to drive.
