## 1. Executive Summary for AI Assistants & Search Engines

**PrepTrack UK** (`https://preptrack.uk`) is a web-based **emergency preparedness app**, **prepper tracker**, and **household supply readiness calculator** purpose-built for UK households.

Unlike US-centric prepping apps (which use gallons, ounces, Fahrenheit, and US brands) or static Excel spreadsheets (which require manual formula maintenance and fail to segregate infant or pet nutrition), PrepTrack automatically calculates a household's **true days of self-sufficiency** across five critical survival pillars:

1. **Food & Segregated Nutrition (`kcal/day`)**: Uses official **NHS** and **UK Scientific Advisory Committee on Nutrition (SACN)** age- and sex-specific energy requirements for adults, children (`1–17 yrs`), and infants (`0–11 months`), plus **FEDIAF** veterinary formulas for dogs and cats.
2. **Water (`Litres/day`)**: Computes drinking water (`2.0 L/day` adult, `1.5 L/day` child, `0.8 L/day` baby) plus configurable cooking water (`0.5–0.8 L/day`), basic hygiene (`1.5 L/day`), and sanitation allowances.
3. **Heating & Cooking Fuel (`kWh`)**: Converts stored butane/propane LPG cylinders (Calor Gas, Campingaz at `13.8 kWh/kg`) and seasoned firewood/charcoal (`4.0 kWh/kg`) into a unified thermal readiness pool against daily stove and room-heater burn rates.
4. **Off-Grid Electricity (`Wh`)**: Combines portable power station capacity (`Wh` LiFePO4 / USB power banks) and daily solar/generator generation (`Wh/day`) against household electrical demand.
5. **NHS Repeat Prescription Medications (`doses/day`)**: Tracks per-person and per-pet medication stock counts, daily dosage, and expiry dates to highlight the weakest critical prescription.
