Most cocktail apps are recipe books. Muddled starts from your shelf. Tell it what bottles you own — it shows every cocktail you can make right now, with green/orange/red dots on every recipe. Green = pour tonight. Orange = one bottle away. The inventory model is what makes it work: mark Bombay Sapphire and Muddled knows you can make any recipe calling for London Dry Gin. No double-entry. 100+ IBA recipes. Recipe sharing. Multi-bar support. $1.99/mo, 14-day free trial.
