Hardtack: Pantry Inventory

Hardtack is the calm, reliable, offline-first home inventory app. Catalog your household reserves (water, food, first-aid, tools, energy, documents) and see at a glance how many days of self-sufficiency your home really has.

Pay once. Own forever. No account, no cloud, no ads, no usage telemetry. Your data stays on your device.

WHAT HARDTACK DOES

• Home inventory, your way
Add items with quantities, units, unit costs and notes. Organize by category and by location: pantry, garage, cellar, vehicle, kit bags and your own custom places.

• Add by barcode
Scan a product and its details fill in automatically: name, brand, nutrition values, net weight and the product image once it is recognised online. Works with UPC and EAN codes. Once a product is identified, its name and nutrition values stay available offline on your device. Manual entry remains available as a fallback.

• Expiry date tracking
An item can carry several dates, each with its own quantity: a product bought more than once stays one item, and the scanner reopens it for the new purchase's date. Local notifications warn you 7 days then 1 day before each date, and a removal eats into what expires soonest first. Nothing slips through forgotten.

• Days of self-sufficiency
A clear dashboard computes your days of water, calories and key reserves from your household composition. Add household members and their needs for a personalized estimate.

• Ready-made kits, and kits of your own
Start from proven checklists: 72-hour bag, vehicle kit, blackout kit, earthquake kit, basic first-aid, infant and pet kits, with visual completion progress. Hide the ones that do not apply, rename, reorder, edit line by line, duplicate, or build your own.

• Smart rotation & restocking
A first-in-first-out view surfaces what to use next. Items below your minimum threshold flow into an automatic shopping list you can export.

• Stock removal & spending tracking
Take a quantity out in one gesture, without deleting the item, or scan your products as you go. Keep an eye on what your reserves cost, with a breakdown by category.

• Privacy controls built in
Optional app lock (Face ID / Touch ID / PIN), item-name obfuscation and a decoy view keep your inventory private on a shared or lost device.

• Local sharing, no cloud
Share an inventory snapshot with family as an encrypted QR code, scanned on the other device, imported locally. No server in the middle.

• Export and back up
Export to CSV or JSON and save a local backup through the native share sheet to Files, Drive or iCloud Drive. Your data, in your hands.

BUILT TO LAST

Hardtack is a one-time purchase, not a subscription treadmill. The free version covers your whole household, expiry reminders and an overall self-sufficiency score, capped at 10 items, 1 storage location, 1 kit template (Bug-out 72h), 1 theme and 1 accent color. The full version lifts these caps and unlocks the detailed self-sufficiency breakdown (water, calories, medication), custom kits, privacy controls, scan-out mode, export and local sharing, all for a single one-time purchase.

Localized in English, French, German and Spanish.
