## Description

QR Analyzer is a visualization and learning tool designed for anyone who wants to understand the internal structure of QR codes.
Unlike typical readers that simply display decoded text, this app reveals how a QR code is constructed through color-coded layers and matrix views.

Key Features
- Capture a QR code with your camera and analyze it instantly
- Color-coded visualization of Finder Patterns, Timing Patterns, Format Information, Version Information, Data modules, and Error Correction (ECC) modules
- Display of mask patterns and the unmasked bit matrix
- Detailed metadata: version, error correction level, mask pattern, size, number of data codewords, and number of ECC codewords

Recommended For
- Students and engineers who want to learn QR code specifications and internal structures
- Developers who need to inspect or debug their own QR libraries or decoders
- Anyone who wants to go beyond simple 'reading' and truly understand how QR codes work

QR Analyzer transforms QR codes from 'a grid of black squares' into a meaningful, structured system you can explore and learn from.
