## What is QuantumShelf?

Know what you have. Share what you need. Never run out again.

QuantumShelf turns your camera into a data-entry clerk. Photograph a package, a receipt, a recipe or a handwritten list, and AI pulls out names, brands, quantities, prices, barcodes and expiration dates for you.

Then it keeps track, reminds you before things expire, tells you where things are, and plans what to do with what you have — across iPhone, iPad and Apple Watch, with one inventory for the whole house.

POINT THE CAMERA, SKIP THE KEYBOARD
• Package scan: name, brand, barcode, expiration date, nutrition and allergens from a photo
• Receipt scan: one photo adds 50+ items with quantities, prices and store name
• Recipe and shopping-list scan from a photo, or paste a recipe link
• AI is powered by Google Gemini and runs on a secure server

PLAN WITH AI
Ask for "a 5-day dinner plan using only what I have" or "an oil change on my truck." QuantumShelf builds ready-to-go projects from your inventory: recipes, the parts and tools you need, step-by-step tasks, and what you're missing. Part numbers appear only when the AI is confident — check them before you buy.

Or just ask: "where's the WD-40?" or "what display cables do I have?" It finds things by what they are, not how you typed them, and tells you where each one lives.

NOTHING SPOILS UNNOTICED
• A daily reminder at the time you pick lists what's expiring soon
• Low-stock and project due-date reminders, each on or off independently
• Color-coded freshness and batch tracking — multiple expiration dates per item
• Drop below a minimum and it lands on the shopping list automatically

MAKE YOUR SHELVES SCANNABLE
• Barcode lookup with check-digit correction for scuffed labels
• Multi-barcode multipliers — scan the can, add one; scan the 6-pack, add six
• Printable 50 × 30 mm QR labels for items, locations and batches
• NFC tags on iPhone: tag a bin, tap to open it

ORGANIZE IT THE WAY YOU STORE IT
• Nested locations — Kitchen → Pantry → Top Shelf — with rolled-up counts
• 94 built-in categories, custom fields (text, notes, number, date, on/off), and unit conversion across cups, grams and counts

PROJECTS AND RECIPES
• Nested checklists, parts and tools checked against what's on hand, shortfalls sent to your shopping list
• Reset a project to run a repeat job again, like the next oil change
• Browse and edit every recipe — fix anything a scan got wrong

ONE INVENTORY, WHOLE HOUSEHOLD
• Invite with a code or a link; four permission levels including read-only, with a full audit trail
• Check items out and in — know who has the drill
• Conflict resolution when two people edit the same item

PAPERWORK AND YOUR DATA
• Seven PDF reports, including insurance documentation and expenses
• Import and export JSON, CSV, Markdown and PDF — lists round-trip with your notes app
• Offline-first, full backup and restore, and Dropbox backup to your own account
• Cloud sync on every tier, including free

EVERY APPLE DEVICE YOU OWN
• Apple Watch app with a complication: shopping list by store, what's expiring, quick quantity changes
• Ten Siri shortcuts: add to the list, find an item, check what's expiring or low
• iPad-optimized layouts

FREE, PRO AND FAMILY
Free covers 50 items, 4 storage locations and 5 AI actions a week, with cloud sync. Pro removes every limit. Family lifts the item and location limits for a whole household of up to six people, with unlimited AI for the subscriber.

## Version history (last 5 releases)

### 2.4.1 — 2026-10-05

2.4 

Photo count: photograph a shelf to stock it, or the counter after cooking to take what you used off. It matches the photo against what's already in your inventory and updates quantities and expiration batches. You review every count before anything saves. Per item you can set the category, expiration date and quantity, or split one product across two dates. If an item already lives somewhere else, it asks whether to add it there or keep a separate item.
Label printing:
QR labels on Avery sheets with any printer, or on Bluetooth label printers from Niimbot, Phomemo and Zebra, plus generic TSPL printers.
You choose up to 40 fields and their order, and fields that won't fit the label size are turned off.
A print queue fills a sheet over time and skips spots you've already used.
Niimbot round and cable-flag labels are supported.
Shared history: History, Usage Trends and the Audit Trail show changes from everyone in the household, on iPhone or Android.
Smaller additions: a Redeem Offer Code button in Settings, and fixes for light mode and for PDF reports that didn't save.
Dropbox backup: listed in the 2.4 release notes, but the build shipped without the Dropbox key, so it shows "not available" for 2.4 users.

2.4.1 

NFC tags open the app even when it's closed: tapping a tag goes straight to that bin or item. Tags written before 2.4.1 need rewriting once. There's also a new NFC scan button on the Dashboard. Someone without the app who taps a tag gets a web page with download buttons.
Share to QuantumShelf: share a recipe or how-to from Safari, Instagram, TikTok, YouTube or Pinterest. Recipe sites import instantly with no AI; posts and videos become a recipe, or a project with parts, tools and steps.
Widgets: Shopping List (check items off on the Home Screen), Expiring Soon (also on the Lock Screen), Low Stock (one tap adds it all to the list) and Quick Actions. There's also a Lock Screen Scan button, and Control Center buttons for Scan, NFC Tag and Add Item.
Bigger free plan: 500 items and 10 locations, up from 50 and 4.
Dropbox backup works.
Cable-flag labels: text now runs along the flag

### 2.4 — 2026-10-01

Two big ones this time.

Photo count
• Photograph the counter after cooking and everything you used comes off your inventory at once
• Photograph a shelf to stock it — set categories, expiration dates and quantities, and split one product across different dates
• Already stored somewhere else? It asks whether to add to that spot or keep a separate item here
• You review every count before anything is saved

Label printing
• Print QR labels on Avery sheets with any printer, or on a Bluetooth label printer: Niimbot, Phomemo, Zebra and TSPL printers
• Pick what goes on each label — name, location, expiration, lot, price, warranty and more — and put it in the order you want
• Queue labels to fill a sheet over time, and skip the spots you've already used
• Niimbot round and cable-flag labels

Also new
