๐Ÿ“ฆ One inventory. Every device.

Know what you have.
Never run out again.

QuantumShelf tracks everything in your home โ€” pantry, garage, tools, gear โ€” and fills in the details for you. Photograph a receipt and add fifty items at once. Track expiration, label bins with QR codes and NFC tags, and share one live inventory across Android, iPhone, iPad, Mac, and Apple Watch.

Know what's about to expire โ€” at a glance

Your dashboard surfaces total items, units, inventory value, low-stock items, and everything approaching its expiration date, with color-coded status you can read in a second.

  • Color-coded freshness: red expired, orange today, yellow soon, green fresh
  • Configurable alert window from 1 to 30 days
  • Low-stock items and expiring batches surfaced automatically
  • Live sync across every device in your household

๐Ÿค– The package fills in its own details

Photograph a product's front, back, and nutrition panel and Google Gemini extracts the name, brand, barcode, expiration date, nutrition facts, and allergens. Printed labels and handwritten dates both work.

  • Auto-fills name, brand, barcode, and expiration date
  • Food: allergens, nutrition, storage instructions, batch numbers
  • Non-food: serial number, model, warranty, condition
  • Powered transparently by Google Gemini

๐Ÿ‘ฅ One inventory. Everyone in the house.

Create a household, invite people with a short code or shareable link, and everyone works from the same live inventory. Four permission levels mean each person gets exactly the access they should have.

  • Four roles: Owner, Admin, Member, and read-only Viewer
  • Real-time sync with conflict resolution โ€” no silently lost edits
  • Complete audit trail, filterable by date and action
  • Sign in with Apple, Google, or email

๐Ÿ” Scan the barcode. Tap the bin.

Scan any UPC or EAN barcode for an instant lookup against Open Food Facts and the UPC Database. Damaged labels still resolve, and a whole shelf becomes something you tap or scan.

  • Automatic check-digit correction rescues scuffed barcodes
  • Multi-barcode per item with quantity multipliers (single can vs. 6-pack)
  • Printable 50ร—30mm QR labels for items and locations
  • Rewritable NFC bin tags โ€” tap to open what's inside

๐Ÿ“„ One photo, fifty items

Photograph a grocery receipt and add the whole trip at once โ€” names, quantities, prices, and store name. Snap a recipe or a handwritten shopping list and it becomes a checklist matched against what you already have.

  • Receipt scan adds 50+ items in a single tap
  • Recipe scan from a photo or a pasted recipe link
  • Shopping-list scan turns a scrawled note into a digital list
  • Unit conversion reconciles cups, grams, and counts

๐Ÿ“ Nest it the way you actually store it

Build storage locations as deep as you need โ€” Kitchen โ†’ Pantry โ†’ Top Shelf โ€” with rolled-up counts, and organize items with a full set of built-in categories plus your own.

  • Unlimited hierarchical locations with rolled-up counts
  • Dozens of built-in categories, plus custom colors and icons
  • Custom fields and field-visibility controls to keep adding fast
  • Batch tracking โ€” multiple expiration dates per item

Everything QuantumShelf Does

A household inventory app that knows what you consume, not just what you own

๐Ÿค– AI Does the Data Entry

Photograph a package, receipt, recipe, or handwritten list and Google Gemini pulls out names, brands, quantities, prices, barcodes, and expiration dates โ€” no typing.

๐Ÿ” Barcodes, QR & NFC

Scan any UPC or EAN with instant product lookup and automatic check-digit correction. Add multi-barcode multipliers, printable QR labels, and tap-to-open NFC bin tags.

โฐ Expiration & Low-Stock

Per-batch expiration tracking with color-coded status and a configurable 1โ€“30 day alert window. Set minimum stock levels and items auto-add to your shopping list.

๐Ÿ‘ฅ Household Sharing

Share one live inventory with four permission levels, from Owner down to read-only Viewer. Real-time sync with conflict resolution and a full audit trail of who changed what.

๐Ÿ”ง Check Out, Check In

Who's got the drill? Check items out to track who has them and when they left, see everything currently out, and check them back in with automatic timestamps.

๐Ÿ“„ Seven Kinds of PDF Report

One tap from inventory to paperwork: insurance documentation, expense reports, complete manifests, reports by location or category, expiration, and low-stock reorder sheets.

โ˜๏ธ Cloud Sync & Offline-First

Add items and scan with no signal; changes sync when you reconnect. Cloud sync is included on every plan, even free โ€” lose your phone and your inventory is still there.

๐Ÿ”“ Your Data Is Yours

Export and import JSON, CSV, and PDF, with a real column-mapping step for imports. Keep a full backup snapshot and auto-back-up to your own Dropbox account.

โš™๏ธ Built to Fit Your House

Custom fields, field-visibility controls, unit conversion, and separate field sets for food and non-food items. Add an item in three taps, not thirty.

Same App, Your Platform

One inventory and the same core features everywhere โ€” then each platform does what it does best
