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]
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]
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]
| Format | Family |
|---|---|
| QR Code | 2D matrix |
| Data Matrix | 2D matrix |
| EAN-13 | Retail barcode |
| EAN-8 | Retail barcode |
| UPC-A | Retail barcode |
| UPC-E | Retail barcode |
| Code 128 | Logistics barcode |
| Code 39 | Logistics barcode |
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]
| Feature | Detail |
|---|---|
| Real-time scanning | Continuous camera scanning with automatic format detection, flash and auto-focus |
| Batch mode | Scan many codes in succession; the app beeps, logs each and keeps looking |
| QR generator | Create codes for URLs, text, contact cards and WiFi credentials; saved to the gallery |
| Open URLs | Offers to open scanned links, set to auto-open or prompt first |
| Share and copy | Copy, share via the Android share sheet, or open in the right app (browser, contacts) |
The app opens fast, decodes in real time, asks for the camera and nothing more, and keeps scan history on the device.[1]
On the Kalenux product page, the app holds an average rating of 4.7 across a moderated review set of 3.[3]
“I downloaded this because of the Play Store rating and it genuinely delivers. Fast scan, full scan history, and the batch scan mode is perfect for stocktaking.”
“We use this in our retail operation for scanning product codes at the point of sale. It’s never failed us and handles damaged barcodes better than alternatives.”
“Scans QR codes and barcodes faster than the built-in camera app on my phone. The offline capability is important for warehouse use.”
