KodokurThe barcode and QR scanner that stays on your phone

Point your camera at any code, from a cereal box to a medicine pack, a book, a Wi-Fi sticker or a poster. Kodokur tells you what it is and what you can do with it, and it never goes online to do it.

One app for every code

Linear barcodes and 2D codes of every common kind: EAN, UPC, Code 128, ITF, GS1 DataBar, QR, Data Matrix, PDF417, Aztec. Held sideways, upside down or printed in reverse, they still read.

Groceries and products

EAN and UPC barcodes on anything you buy. Look a product up in Open Food Facts or search the web in one tap.

Medicine codes

The square code on a medicine box shows its expiry date, batch and serial number in plain words, and Kodokur warns you if the date has passed.

Books and magazines

ISBNs come out properly hyphenated, with the ISBN-10 and the country or language group. Magazine barcodes give the ISSN and issue number.

Wi-Fi

Join a network from its QR code in one tap. The password stays hidden until you choose to see it.

Contacts and more

Business card QR codes go straight to your contacts. E-mail, phone, SMS and map codes open the right app.

Small codes, old photos

Pinch or double-tap to zoom in on tiny barcodes, and read a code from a photo without giving camera access.

Know where a link goes

QR codes on posters, parking meters and menus are an easy way to send people to fake sites. Before you open a link, Kodokur shows the site it really leads to and warns you when something looks wrong.

kotu.example
The part before “@” is only a user name. The link really goes to kotu.example.

It also flags addresses written with look-alike letters from other alphabets, links to bare IP addresses and unencrypted http pages, and asks before opening any of them.

Stock-taking and cataloguing

Batch scanning and CSV

Batch mode adds code after code to the history without stopping and never counts the same item twice. Share the list as a CSV file for a spreadsheet: a shop shelf, a pharmacy cabinet or a home library.

Stays on your phone

The app has no internet permission. The only permission is the camera; frames are examined on the phone and never saved or sent anywhere. Buttons such as product or book search hand the code to your browser. Your history stays on your phone and, because it can contain Wi-Fi passwords, is left out of backups. Privacy policy
