Free tool · One intentional shopping run
Turn "be prepared" into a shopping list.
Every preparedness page says "store enough water and food". This one does the arithmetic: who's in the household, how many days to cover, and out comes a list you can shop from. Built on published federal planning figures, math done in your browser, nothing stored.

Days to coverFederal guidance says at least several days; in hurricane country many emergency managers suggest up to two weeks at home
Where the figures come from: the water line follows ready.gov, which says to "store at least one gallon of water per person per day for several days, for drinking and sanitation", and notes that children, sick people, hot climates, and medical events can push needs higher (in very hot temperatures, water needs can double). The food line follows ready.gov's "at least a several-day supply of non-perishable food" with its no-cook item list. Pet water is our planning estimate, marked as such. Sources and phrasing are logged in VERIFY.md (V1, V24, V25, V2).
Planning arithmetic, not medical or nutritional advice: prescription needs belong with your pharmacist and doctor, and special diets, infants, and medical equipment change the list. The 48-Hour Checklist is the when-a-storm-is-coming companion; the readiness check tells you whether supplies are even your biggest gap.
