Everything in Infinity Lists can be customized to fit your specific needs. Lists can be as simple as this week's groceries, but the real value of Infinity Lists is in its powerful customization tools. If you're looking for customization and complete control, put this on your to-do list: buy Infinity Lists from the App Store." -- Mac|Life (5/5 stars) Rating: 'Awesome' "Customization out the wazoo. Very nice interface for such a full-featured app. It works almost precisely the way you expect an iOS app to work, and it's jam-packed with features that leave it balancing lightly on the line between a powerful list app and a simple database. And yet, with all these complexities, the lists themselves are easy to use, easy to organize, and easy to update." -- Wired (9/10 stars) Rating: 'Nearly flawless: buy it now' "Exactly What a List App Should Be. They've brought something new to a genre that is otherwise tired and cluttered with generic developments. Infinity Lists is easily one of, if not the best list app for iPhone and iPad that we've ever seen." -- appPicker "It's clearly a very flexible app. It is quick and easy to use, works seamlessly between iPhone and iPad versions, and syncs easily. This is a great tool that will work perfectly for most tasks you have." -- c|net "Your complete List Assistant. We have yet to find anything more complete than Infinity Lists." - appsplit Featured in Apple's New & Noteworthy Apps Terms of Use - https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Customer Service is a top priority.

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.
