Build a QR Code Scanner App
— Scan Everything Instantly
Build a QR code scanner with instant scanning, history, QR code generation, and batch scanning.
Why Build a QR Code Scanner App?
QR codes are everywhere — payments, menus, event tickets, and product information. A dedicated scanner app provides a faster, more reliable experience than built-in camera apps.
A QR scanner needs fast camera-based scanning, support for multiple code formats, scan history, QR code generation, and the ability to act on scanned content (open URLs, copy text).
Fastshot generates a native QR scanner with instant scanning, code generation, scan history, and content actions for iOS and Android.
You can build this qr code scanner app using our AI mobile app builder — describe what you want and get a working native app in minutes.
