QR Studio

What problem it solves QR Studio eliminates the need for multiple tools or websites by combining QR code generation, scanning, and management into one privacy-first, offline-capable app. Users no longer need to search for separate generators, worry about ad-filled scanners, or lose track of QR codes they've created. Main features Generate QR codes for 12 categories: WhatsApp, Facebook, Instagram, LinkedIn, URL, Text, Email, SMS, WiFi, vCard, Calendar, and Location — each with a tailored input form Scan QR codes in real-time via camera or decode them from gallery images Customize QR codes with 16 colors and high-resolution rendering Organize codes into built-in and user-defined custom categories with custom icons and colors Search, sort, and filter saved QR codes; mark favorites for quick access Export/import all data as JSON backup files View scan history (last 50 scans) Material 3 design with System/Light/Dark theme support Who should use it Anyone who regularly works with QR codes — small business owners, freelancers, social media managers, event organizers, or general smartphone users who want a reliable, ad-free, all-in-one QR code tool. Why it is useful All data stays on-device with no tracking or ads. The app works offline, combines generation and scanning in one place, and helps users stay organized with categories, favorites, and search — making it a practical daily driver rather than a throwaway utility.
