QR & Barcode Scanner

Scanning a code should be instant, not invasive.

Point the camera and codes decode in real time: QR, Data Matrix, EAN, UPC, Code 128, Code 39 and more, with every scan saved to history, batch scanning for stocktakes, CSV export and a built-in generator. It asks for the camera and nothing else.

QR & Barcode Scanner is a multi-format QR code and barcode scanner for Android developed by Kalenux, with a built-in generator, automatic scan history, batch scanning and CSV export.[1] It requests only camera permission and keeps scan history on the device, so a stocktake never leaves the phone.[1]

Overview

The scanner uses the device camera to detect and decode codes in real time, with automatic focus and flash control for difficult lighting. It recognises QR codes, Code 128, EAN-13, EAN-8, UPC-A, UPC-E, Code 39, Data Matrix and other common formats without the user specifying the format in advance.[1]

The app works in both directions: scanning codes that come from the outside world, and creating codes to share with others.[1]

History and motivation

Kalenux describes the scanner category as a minefield: ad banners covering the viewfinder, full-screen interstitials between scans, trackers logging where users go, and permission prompts for contacts, location and storage. Its position is that a QR reader has no business knowing who the user calls or where they are.[1]

“So we built a scanner that does the job and nothing else.”[1]

Scan history and export

Every scan is saved automatically with a timestamp, the decoded value and the format type. Any entry can be opened, copied or shared, and the full history can be exported as CSV: useful for inventory counts, asset tracking and any workflow where scanned data is processed in a spreadsheet or database.[1]
