When something goes wrong — a natural disaster, a power outage, a supply chain collapse — you won't have time to figure out where your family stands. You need to already know. Underground Prepper is a family emergency preparedness app built around one core idea: knowing exactly what you have, where it is, and whether it's enough — before you ever need it. --- YOUR DATA STAYS ON YOUR DEVICE Underground Prepper is built privacy-first. Every item in your inventory, every household member profile, every checklist — it all lives in an encrypted database on your device. Nothing personal ever touches our servers. The app works fully offline, by design, because the moment you need it most is often the moment the internet goes down. --- TRACK YOUR PREPAREDNESS TIER The app measures your family's readiness across four tiers — 3 days, 3 weeks, 3 months, and beyond. Your current tier updates automatically as you build your inventory. No guesswork. No spreadsheets. Just a clear picture of where you stand and what you still need. --- MANAGE YOUR FULL INVENTORY Organize your supplies across 14 categories: Food, Water, First Aid, Security, Power, Communications, Tools & Hardware, Clothing & Gear, Sanitation & Hygiene, Medications & Supplements, Financial & Documents, Fuel, Camping & Shelter, and Seeds & Agriculture. Every item tracks quantity, expiration dates, storage location, owner, and — for food — calories per serving. Expiration warnings surface automatically. Built-in recommended items lists help you get started fast. --- BUGOUT BAGS FOR EVERY MEMBER Every household member gets their own bugout bag. The app tracks five milestones per bag — Food, Water, Shelter, Defense, and First Aid — and shows exactly how many calories and how much water each person still needs to reach their goal. --- HOUSEHOLD MEMBER MANAGEMENT Add your entire household with individual calorie and water requirements calculated from age, gender, height, and weight. Members can have their own PIN-protected access. As the account administrator, you control who can view or modify data at all times. --- INVENTORY REPORTS View and export your inventory eight ways: by owner, category, storage area, expiration date, power requirements, season, gender, and tradable items. Every report can be printed or saved as a PDF. --- BACKUP & RECOVERY Export your inventory as a CSV or encrypted .prep backup file protected by a 12-word recovery phrase only you know. Optionally push an encrypted backup to the server for an extra layer of protection — our server stores only the encrypted data and can never read it. --- PREP HUB & BIBLE READER Access a library of printable preparedness checklists covering bugout bags, water storage, medical supplies, power, navigation, and more. We believe preparedness goes beyond supplies. The built-in Bible reader — available in King James and Douay-Rheims — is there for the moments when what your family needs most isn't in the pantry. --- Try the app free with Demo Mode — no account required. When you're ready, subscriptions are available monthly, yearly, or as a one-time lifetime purchase. Underground Prepper is an organizational and inventory tool only. It does not provide medical, survival, or safety instructions, and should not be relied upon as your sole source of emergency guidance. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ --- Underground Prepper. Know where you stand.
