Know what
you have.
A photo-first, offline inventory tracker for solo sellers, collectors and households. Catalog five products in under five minutes โ then update stock with one tap or one scan.
Free to start ยท No account required ยท Your data stays on your iPhone
Simple inventory, done properly.
No warehouses, no team roles, no sales calls. Just the tools a one-person operation actually uses.
Photo-first products
Snap a photo, add a name โ your product card is ready. A picture beats a spreadsheet row every time.
One-tap counting
Adjust stock with big +/โ buttons. Every change is logged automatically, so counts always add up.
Barcode scanning
Point the camera at a barcode to restock in a second โ or create a new product with the code pre-filled.
Low-stock warnings
Set a threshold per product and see at a glance what needs restocking before it costs you a sale.
Movement history
Restocks, sales, corrections โ a full audit trail of every quantity change, with timestamps.
CSV import & export
Bring an existing list in, take your whole inventory out. Your data is never locked in.
Up and running in five minutes.
Pick the way that suits how you already work โ Kantro sets it up as your first step.
Add it yourself
Start with a photo and a name. Quantity, price and location are one screen away โ all optional.
Scan a barcode
Use the camera for faster entry. Known barcodes restock instantly; new ones open a pre-filled form.
Import a CSV
Already keep a list in Excel or Numbers? Bring it with you in one import โ duplicates are caught for you.
๐ก๏ธ Your inventory stays yours.
Kantro has no accounts, no ads and no analytics trackers. Your products, photos and numbers live in a local database on your iPhone โ we never see them, and we don't operate any servers.

Questions, answered.
Do I need an account?
No. Kantro works entirely without sign-up. Open the app, add your first product, done. There is no login screen anywhere.
Where is my data stored?
In a local database on your iPhone. Nothing is uploaded to us โ we don't operate servers. It's included in your normal iOS device backups, and you can export a CSV anytime.
Does it work offline?
Completely. Count stock in a basement, a storage unit or a craft fair with no signal โ everything works, always.
Who is Kantro for?
Solo sellers on Etsy, eBay or Vinted, market and craft-fair traders, collectors, and anyone organizing a home. If a full inventory platform feels like overkill, Kantro is for you.
How does the free trial work?
Kantro Pro comes with a 3-day free trial on the yearly plan. Cancel anytime in your Apple Account's subscription settings โ note that deleting the app does not cancel a subscription.
