Easily, you can read, generate, and manage QR code reading history. While many similar QR apps display numerous ads, this app has no embedded advertisements, allowing for uninterrupted scanning and a stress-free experience. QR Code Scanning Upon launching the app, the QR code scanning screen is displayed immediately, allowing you to scan QR codes without delay. The scanned data can be opened and verified in an external browser. QR Code Generation You can create your own unique QR codes. You have options for color, shape, and embedding images to produce distinctive QR codes. Once generated, the code can be quickly shared (on platforms like Line, Facebook, X, etc.) or saved. QR Code Reading History You can check previously scanned QR codes, allowing you to review the scanned data (either URL or text) at a later time.
