QR code

Your phone already has a camera. But can it turn a textbook page into a live 3D model, decode a damaged barcode from a crumpled receipt, or generate a scannable code for your next biology quiz? Most QR scanners stop at showing a link. This app transforms your device into a full-featured educational toolkit, built specifically for students, teachers, and researchers who need to extract, create, and manipulate QR data without ads or artificial limits.

Core Capabilities

The application operates as a dual-mode scanner and generator, optimized for Android 9 and above. The scanning engine processes standard QR, Data Matrix, Aztec, and PDF417 symbologies, reading codes from live camera feed, saved screenshots, or image files up to 4096x4096 pixels. For damaged codes, the adaptive error correction algorithm rebuilds missing modules up to 30% of the surface area, using Reed-Solomon redundancy decoding. The generator module supports custom payloads: plain text, URLs, vCard contacts, calendar events, Wi-Fi credentials, and GeoLocation coordinates. Each generated code exports as PNG, SVG, or EPS vector format, with user-defined foreground color, background transparency, and module size between 8x8 and 100x100 pixels.

Educational Features

• Batch decode mode: Processes up to 50 images from gallery or folder in one pass, exporting results as CSV or JSON for data analysis projects
• Live overlay projection: Superimposes decoded text directly onto the camera view, enabling hands-free reading during lab experiments or field research
• Custom error correction level: Manually set L (7%), M (15%), Q (25%), or H (30%) recovery capacity to match physical code condition before scanning

Key Advantages

• Offline operation: All scanning and generation executes locally on device — no internet connection required for any core function
• History log with search: Stores last 500 scans with timestamp, type, and content preview, filterable by date range or payload category
• Zero advertisement policy: No banner ads, interstitials, or sponsored results interrupt the scanning workflow or result display
• Accessibility support: VoiceOver and TalkBack compatible, with haptic feedback on successful decode and adjustable vibration patterns

Technical Disclaimer

This app requires an active internet connection for optional cloud backup and software update checks. Scanning and generation functions operate fully offline. In-app purchases exist for premium export formats (SVG, EPS) and batch processing capacity expansion. No user data is collected, stored, or transmitted to third parties.
