Answer a few calm questions. Get a Ready.gov-aligned water total, food days, and a shopping list that fits this week’s budget — no scare tactics.
Three short steps. No account. Nothing is stored on our server.
Adults, kids, pets, house or apartment, and an optional region hazard.
Start with 3 days (Ready.gov minimum) or aim for 2 weeks. Set what you can spend this week.
Water gallons, food days, “start this week” steps, storage tips, and a printable view.
Water math uses 1 gallon per person per day (Ready.gov / FEMA). Pets add about 0.5 gallon per pet per day. Adjust anytime — this is a planning aid, not an order form.
Not medical advice. This checklist is general education from public Ready.gov, FEMA, CDC, and Red Cross materials. It does not replace local emergency instructions or advice from your doctor.

Think of a basic kit the way you think of insurance for ice storms, hurricanes, or a multi-day outage — useful when life is inconvenient, not a prediction that something terrible is about to happen.
Official baselines, not rumors. We cite Ready.gov, FEMA, CDC, and Red Cross numbers you can verify yourself.
Buy a little each trip. A weekly budget turns a big list into ordinary grocery stops.
Apartment-friendly options. Stack water cases; skip advice that only works with a huge garage.
No doom copy. No fake testimonials, no countdown clocks, no claims that a specific catastrophe is imminent.
Straight answers. Same questions are marked up for search assistants.
Ready.gov and FEMA recommend at least 1 gallon of water per person per day. Plan for a minimum of 3 days; try for 2 weeks if you can. Pets need extra water on top of the people total.

Not required. Enter a weekly budget and the builder splits the list into “start this week” steps so you can add a little on regular grocery trips — the same approach Ready.gov suggests.
You can optionally pick winter storms, hurricanes, wildfire, flooding, earthquakes, or an extended power outage. The core water and food math stays the same; the tip list adds a few hazard-specific ideas.
