■ A tool for "reading, researching, and creating" barcodes/QR codes

Barcode Lab is a tool app that allows you to scan barcodes and QR codes with your camera and analyze their contents in detail. You can see the standard type,
country code, and check digit verification at a glance. It also includes barcode generation and a standards dictionary, making it useful in development, inspection, and learning environments.
