Winter Stock

Winter Stock is an offline calculator that works out how much food and water your family needs to stock up for a chosen period — a week, a month, the winter, or a full year. It's built for planning reserves in situations where access to stores or the internet might be limited. How it works: Enter your family's makeup — men, women, children by age group, pregnant or breastfeeding members, physical activity level. Pick your stockpiling period and diet type: regular, vegetarian, or vegan (with a note on vitamin B12). Add your region and climate zone, and the calculator accounts for seasonality and local crop availability. What you get: - Detailed breakdown by category: grains, legumes, fats, sugar, salt, protein, vegetables, preserves - Total weight and estimated volume of the stockpile - A separate water calculation — an emergency buffer plus a long-term reference figure, with tips on sources and purification - A shopping checklist right in the app — your progress is saved - Export the shopping list to PDF (print-ready) or CSV - Save multiple scenarios (e.g. "family for winter" and "family plus relatives") - Storage-loss buffer and a contingency reserve — both adjustable Why this app: - Fully offline — no internet needed for calculations or everyday use - No ads, no in-app purchases, no accounts - Your data stays on your device - Available in 22 languages A minimal, clear interface designed to stay easy to use even under stress.
