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, custom places).

• Add by barcode: scan a product and its details fill in automatically. UPC and EAN codes are supported, and the online lookup fills in name, brand, nutrition values, net weight and the product image once it is recognised. 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: one date per item, local notifications 7 days then 1 day ahead, and a removal that 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 members and their needs for a personalized estimate.

• Ready-made kits, and kits of your own: 72-hour bag, vehicle, blackout, earthquake, basic first-aid, infant and pet kits. Hide, 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, exportable shopping list.

• Stock removal & spending tracking: take a quantity out in one gesture without deleting the item, or scan your products as you go, and keep an eye on what your reserves cost.

• Privacy controls built in: optional app lock (fingerprint / face / 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 and 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 your storage of choice.

BUILT TO LAST

Hardtack is a one-time purchase, not a subscription treadmill. A free tier lets you start, with your whole household, expiry reminders and an overall self-sufficiency score. The full version lifts the item and location caps, and unlocks the detailed self-sufficiency breakdown (water, calories, medication), every kit template and custom kits, all themes, privacy controls, scan-out mode, export and local sharing, all for a single one-time purchase.

Available on Android and iOS, localized in English, French, German and Spanish.

FREQUENTLY ASKED QUESTIONS

Does Hardtack work offline, without an account?

Yes. Inventory, expiry dates, reminders, grocery list and days of supply all work with no connection, no account and no email. Only the optional product lookup when you scan a barcode queries a product database, and it sends nothing but the barcode.

Is this a subscription?

No. The full version is a single one-time purchase. Nothing renews, nothing is rented by the month.

How does expiry date tracking work?

Each item carries its expiry date. Hardtack warns you 7 days then 1 day ahead, and the first-in-first-out view tells you what to use before it goes to waste.

What are kit templates for?

So you never start from a blank page: 72-hour bag, vehicle kit, blackout kit, earthquake kit, basic first-aid, infant and pet kits.
