Tell it who lives with you and how long you want to be ready for. It works out the water, food, cooking gas, batteries, toilet and warmth supplies, using the quantities in the UK Crisis Survival guide, and gives you a shopping list to tick off and print.

Your shopping list

Tick what you already have; the ticks are remembered on this device. Build it in stages: water and the first two weeks first. Buy food you already eat, and rotate it.

Quantities are scaled from the UK Crisis Survival guide's lists for a family of four (2 adults, 2 children: about 8,000 kcal and 12 litres of drinking water a day), rounded up. Calories: adults 2,250 a day (2,500 in winter), teenagers 2,600, children 1,750, toddlers 1,100, plus 350 for pregnancy or breastfeeding. Water: 3 litres per person per day minimum, 10 for drinking, cooking and basic washing (UK Government advice). Adjust for your family's appetites, health and tastes.
