Baccalculator

I built bac-calculator.xyz after a friend almost lost everything to a DUI. My goal was simple: give people a fast, honest tool that tells them—without judgment—whether they’re safe to drive. Plug in gender, weight, drinks and time; the site spits out your BAC, shows how it drops hour-by-hour, and flat-out warns you if you should call a cab. It’s mobile-first, lightning-fast, stores zero data and will stay free forever. Use it for yourself, share it with friends, maybe save a life tonight.
