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.

Meet your prep buddy. BeaglePrep keeps your pantry, supplies, and emergency stock organized — calmly, privately, with no account and no subscription. Add your first item in seconds and let your prep buddy watch your stock, nudge you before things expire, and cheer as your Prep Score climbs. Whether you're building an emergency kit, managing a deep pantry, or putting up a canning season, you'll always know what you have and what you need. Free to use. No account. Works offline — your data stays on your device. NEW: CONTAINERS INSIDE CONTAINERS Put a bin in a closet in the basement, up to 12 levels deep. Tap into any container to see what's inside, move a whole container with everything in it, and restore a deleted container from Trash with its contents intact. SCAN A PANTRY ITEM IN UNDER 10 SECONDS Point your camera at any barcode and BeaglePrep fills in the name, brand, and size automatically. Results are drawn from Open Food Facts and USDA FoodData Central and cached on your device, so repeat scans work even with no signal. Not in the database? Fall back to quick manual entry. ONE NUMBER THAT ANSWERS "AM I ACTUALLY READY?" Set your household size — adults, kids, pets — and the Prep Score shows how many days of supply you have in each category against your targets, from food and water to medical, hygiene, and cleaning supplies. The score updates as you stock up, and the checklist shows you exactly where the gaps are. A CANNING SEASON THAT TRACKS ITSELF Put up a big batch of sauce or pickles and BeaglePrep remembers it all: how many jars, the day you sealed them, and when to eat them by. Use-by reminders rotate last year's jars first, and smart grouping keeps "Tomato Sauce x12" as one tidy card instead of twelve rows. TRACK WHAT MATTERS • Quantities, units, and storage locations for every item • Containers inside containers, so you know which bin to open • Expiration dates with "expiring soon" alerts so nothing goes to waste • Restock thresholds — get a low-stock badge when supplies run low • Categories: Food, Water, Medical, Tools, Fuel, Hygiene, Comms, Shelter, and more • Locations for wherever you keep supplies: Pantry, Garage, Car, Bug-Out Bag FAST TO USE, EASY TO MAINTAIN • Scan barcodes to auto-fill item details • Quick-Add remembers your last-used category and unit • Autocomplete from a built-in dictionary of 1,400+ common prepper supplies • Inline quantity editing right from the main list • Search finds items even inside collapsed containers • Sort and filter by name, quantity, category, location, expiry, or "expiring soon" • Bulk move, update quantities, or delete items — and undo a delete if you change your mind REMINDERS THAT KEEP YOU ON SCHEDULE • Expiration reminders with the date and a countdown, soonest first • Recurring tasks — rotate water every 6 months, inspect gear annually • Notifications so nothing slips through the cracks YOUR DATA, YOUR WAY • Works offline — no account required • Automatic on-device backups, free and private • Export your inventory to CSV anytime • Works with large text sizes and VoiceOver FREE, WITH AN OPTIONAL ONE-TIME PRO UPGRADE Free includes the full core experience: inventory, Prep Score and supply targets, barcode scanning, smart grouping, reminders, and rotation tasks — up to 75 items and 10 locations, containers included.
