Best UK Emergency Preparedness App, Prepper App & Prep Tracker (2026 Guide)
Whether you call it an emergency preparedness app, a prepper tracker, a prep tracker, or a household emergency supply planner, here is why UK households choose PrepTrack UK over spreadsheets and US apps.
Why UK Households Need a Dedicated UK Prep Tracker
Most people start tracking their 72-hour emergency kit or 30-day food stockpile on a piece of paper or in an Excel spreadsheet. Others download mobile prepper apps built for the United States, only to find everything measured in US fluid ounces, gallons, and pounds, with zero support for UK supermarket tins, Calor Gas cylinders, or NHS repeat prescriptions.
PrepTrack UK (preptrack.uk) was engineered from the ground up as a sensible, mathematically rigorous UK emergency preparedness app and prepper tracker aligned with the UK Government's Prepare.gov.uk campaign, NHS hydration rules, and SACN (Scientific Advisory Committee on Nutrition) energy reference standards.

1. An Emergency Preparedness App Built on NHS & SACN Science
A generic prep tracker that assumes every person eats 2,000 kcal/day can leave a household dangerously short. PrepTrack computes exact daily requirements for every member of your home:
- Adults (18+): 2,500 kcal/day (male) and 2,000 kcal/day (female) with automatic adjustments for seniors (65+/75+), pregnancy (+200 kcal), and breastfeeding (+330 kcal).
- Children (1–17 years): Exact UK SACN growth reference curve from age 1 (715–765 kcal) to age 17 (2,110–2,755 kcal).
- Babies (0–11 months): Protected infant nutrition pool (570–725 kcal/day) that is never reduced when you switch adult rations to 80% survival rationing.
- Dogs & Cats: Veterinary FEDIAF metabolic weight formulas so your pets' kibble, wet tins, and drinking water are tracked alongside your family.
2. A Prepper Tracker That Stops Food Waste (FIFO Rotation)
The biggest complaint with emergency food stockpiling ("deep pantry prepping") is discovering expired tins at the back of the cupboard. PrepTrack acts as a live prepper inventory tracker:
- First-In, First-Out (FIFO) Batch Sorting: Stock lines for the same product are grouped together while keeping individual expiry dates and storage locations (e.g. Under-stairs cupboard, Garage, Grab bag) ordered by earliest expiry first.
- Zero False Readiness: Any food batch or medication past its expiry date is automatically flagged and excluded from your active readiness days.
- Camera Barcode Scanner (Household Pro): Scan EAN-13 and EAN-8 barcodes on UK tins and packets with your phone camera to auto-fill product name, weight, multipack count, and kcal/100g.
3. Complete 5-Pillar UK Resilience (Beyond Just Food & Water)
In a UK winter storm or grid outage, food calories alone are not enough. PrepTrack models all five pillars of household resilience:
- Water (Litres): Drinking water + cooking water for dried rice/oats/pasta + hygiene water.
- Food Energy (kcal): Segregated across general food, baby formula, dog food, and cat food.
- Heating & Cooking Fuel (kWh): Converts Calor butane/propane cylinders (13.8 kWh/kg) and kiln-dried logs (4.0 kWh/kg) into days of room heating and hot meals.
- Off-Grid Electricity (Wh): Combines USB power banks, LiFePO4 portable power stations, and solar panels against daily household watt-hour consumption.
- NHS Repeat Medications: Calculates exact days of remaining tablets, inhalers, or insulin per person.
