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.

Already subscribed and setting up on a new device? The sign-up screen now guides you back in with a new setup code instead of a dead end. -Smoother first-time setup. Reopening the app mid-signup now takes you straight back to finish registration, and never shows sample/demo accounts by mistake.Mac printing fixed. Inventory reports now open the standard macOS print dialog and print correctly. ### 2.1.18 — 2026-07-18 What's New — 2.1.18 -Fixed an issue where some members were incorrectly shown as "read only" after buying or restoring a subscription. -You can now renew an expired subscription directly from the app. -Added a "Restore from a backup file" option on the sign-up screens, so it's easier to recover your data on a new or reinstalled device. -Fixed the "Copy phrase" button on Mac. -Improved back navigation on the restore screen. -Reliability and behind-the-scenes improvements. ### 2.1.16 — 2026-07-16 What's New — 2.1.16 - Fixed printing on iPhone and iPad — checklists and reports now print with the correct layout and icons. - Added the app version number to the account menu. - Resolved an issue that could prevent a subscription from activating after purchase. ### 2.1.14 — 2026-07-15 What's new in 2.1.14 Backup & Recovery Fixed an error that prevented new subscribers from saving their first backup to the server. Fixed an issue where restoring a backup could give a read-only family member account holder access. Your existing data is now protected if a restore is interrupted — previously an interrupted restore could leave the app with no data. Family members with read-only access now see "Wipe & Restore" instead of "Merge" when pulling from the server or importing a backup file, since read-only members don't make changes of their own. Improved the security of recovery phrase generation. Bugout Bags Fixed water requirements on accounts with more than one family member. Each person was being asked to carry enough water for the entire family, so bugout bags showed a water shortage that wasn't real. Demo Mode Updated the sample family's inventory so the bugout bag examples are more complete. Printing Print buttons now work on phones and tablets. Reports and checklists can be printed or saved as a PDF. Purchases Fixed an issue where the app could become unresponsive after completing a purchase. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
