"NX1 is your personal AI that lives in your home — not in the cloud. This app is the companion to the NX1. The NX1 connects to your own accounts, and runs its intelligence entirely on hardware you own. The app requires a NX1 device to function. PRIVATE BY ARCHITECTURE, NOT BY POLICY Your email, finances, health data, and location never touch any servers — we couldn't read them if we wanted to. Everything is processed by the AI model running on your NX1 at home. All data between app and NX1 travels direclty between them. Your location is used only on your phone. There is no account with us, no data collection, nothing to breach and nothing to sell. When we say your data is yours, we mean it. A BRIEFING, NOT A FEED Every morning: how you slept, what your body's ready for, what's due, what's arriving, what needs a decision. Every evening: how the day went. In between, NX1 stays quiet unless something genuinely needs you — it sends a handful of notifications a day at most, respects your quiet hours, and never manufactures urgency. Silence means you're covered. A PLACE TO PUT EVERYTHING Type ""milk, bread, vitamins"" and forget it — your list appears when you walk into the grocery store. Snap a photo of a receipt, a bill, or your lunch. Send a thought, a reminder, a question. No folders, no tags, no filing. NX1 organizes everything and brings it back exactly when and where you need it. YOUR MONEY, WATCHED Duplicate charges caught. Forgotten subscriptions surfaced, with the yearly total. Bills flagged before they're due. Your investment portfolio understood the way an advisor would see it — including what's really inside your index funds, so you know your true exposure across every path you own it. YOUR HEALTH, IN CONTEXT Readiness each morning from your own baselines — not generic targets. Meals logged from a photo. Patterns noticed across your life: how sleep tracks your activity, what your calendar does to your body. NX1 compares you to you. ASKS, NOT ASSUMPTIONS When something needs a decision — trust a new sender, confirm a trade record — NX1 asks with one tap in your stream. Nothing important happens without you. WHAT YOU'LL NEED • An NX1 device (autonomynext.com) • An iPhone with iOS Version 26 or above NX1 is for people who want one calm, trustworthy place where their life makes sense — without handing that life to a cloud."

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.
