QR Analyzer

QR Analyzer is a visualization and learning tool designed for anyone who wants to understand the internal structure of QR codes. Instead of simply displaying decoded text like a typical QR reader, this app reveals how a QR code is constructed by showing its modules with clear 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 ECC (Error Correction Code) modules - Display of mask patterns and the unmasked bit matrix - Detailed QR metadata: version, error correction level, mask pattern, size, number of data codewords, and number of ECC (Error Correction Code) codewords Recommended For - Students and engineers who want to learn QR code specifications and internal structure - 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.
