Barcode Organizer is a versatile inventory management app for both personal and professional use. It allows users to create, print, and scan barcodes and QR codes for efficient product management.

Key Features:

  • CREATE: Generate barcodes (QR Code, EAN-8, EAN-13, UPC-A, CODABAR) for items and organize them like a professional catalog.
  • PRINT: Print barcodes on labels, paper, or PDF for easy application.
