## What it is
Binary Eye is a free, open-source, ad-free barcode scanner app for Android built on the ZXing-C++ library. It reads a wide range of barcode formats in any orientation, including inverted codes, and can also generate barcodes.

## Use cases
- scan qr codes on android
- read barcodes with camera
- generate qr codes for free
- scan inverted or rotated barcodes
- decode data matrix and pdf417 codes
- open-source alternative to proprietary scanner apps

## When to choose
- you need a free, ad-free barcode scanner on Android
- you want to both scan and generate barcodes
- you prefer open-source apps from F-Droid

## When to avoid
- you need barcode scanning on iOS or desktop
- you need a scanning library to embed in your own app rather than a standalone app
