Barcode inventory app: scan the code, get the whole product
By mise · Updated October 6, 2026
Quick answer: a barcode inventory app reads each product's UPC or EAN with your phone camera or a Bluetooth scanner, so you count and track stock by scanning instead of typing. Many barcode apps only read the number and make you type the product details once per item; mise also returns the product — name, brand, photo, category and size — and its AI finds the ones it doesn't know yet. 7-day free trial, no card.
Scanning is the easy part — every phone can read a barcode. The question is what happens after the beep: does the app know what you just scanned, or does it ask you to type it in?
How barcode inventory works
The barcode on a pack — a 12-digit UPC in the US and Canada, a 13-digit EAN almost everywhere else — identifies the product, not the unit. Every 750 ml bottle of the same vodka carries the same number. So barcode inventory is simple: scan to say what, type to say how many. The difference between apps is how they get from the number to the product. (More on the formats in UPC vs EAN vs GTIN.)
Reading the barcode vs knowing the product
| Typical barcode inventory app | mise | |
|---|---|---|
| First scan of a new item | "Item not found — create it": type name, size, category, take a photo | Name, brand, photo, category and size come back |
| Unknown or local product | You type it | The mise AI finds it from the barcode or a photo of the label |
| Next scans | Finds the item you created | Same product, already categorized |
| What you type | Product details + quantity | Quantity only |
Phone camera or Bluetooth scanner?
The phone camera is enough for most counts and for receiving deliveries. If you scan hundreds of items in one go, or work in dim stockrooms, a Bluetooth barcode scanner is faster; mise supports both, and a Bluetooth scale for anything sold by weight or by the pour.
Items without a barcode
Fresh produce, portions, kegs, items you make yourself: add them once by name or with a photo of the label, then count them like everything else. Labels printed in-store for weighed items start with a 2 and only exist inside that store, so treat those the same way: add the item once by name.
What you do after scanning
- Count by location — see inventory count app.
- Receive deliveries from the invoice and record waste with a reason.
- Set par levels and get an order list.
- Compare counts for variance and COGS, and export to Excel, PDF or CSV.

Frequently asked questions
What is the best barcode inventory app?
One that recognizes the product from the barcode instead of making you create every item, counts by location with partial units, works offline and exports. mise does that on iPhone, Android and the web.
Is there a free barcode inventory app?
Free barcode apps usually limit the number of items or make you type each product. mise is free for 7 days with everything included and no card, then US$33 a month.
Do I need a barcode scanner?
No. The phone camera reads barcodes. A Bluetooth scanner is optional and worth it for very large counts.
Does it work on Android and iPhone?
Yes: Google Play, the App Store and any web browser, with one account.
What happens if a barcode isn't recognized?
mise's AI researches the code and identifies the product; you can also take a photo of the label. Codes starting with 2 are labels printed inside a store, so add those items once by name.
