Use the iPhone Camera when you just want to open a single web link in front of you. Use QR Code Reader & Generator when you need to scan 1D barcodes (UPC, EAN, Code 128, PDF417), decode screenshots or files, keep a scan history, inspect full URLs safely before opening, batch scan multiple items, or create custom QR codes with your logo and brand colors.

Where a Dedicated QR & Barcode App Wins
1. Retail, Books & Logistics Barcodes
Point the default iPhone Camera at a book's ISBN barcode, a grocery item's EAN-13/UPC-A barcode, or a shipping label's Code 128 / PDF417 barcode and nothing happens. QR Code Reader & Generator decodes all of them immediately and lets you copy the number or search the product online.
2. Screenshots, Photos & Files
When someone sends you a QR code for an event ticket, Wi-Fi login, or payment in a chat message or PDF, you can pick the image directly via Scan from Photos or Scan from Files—even when iOS Live Text fails to detect stylized or non-URL QR codes.
3. Creating & Validating Custom QR Codes
Need to share your home Wi-Fi with guests or hand out a digital business card at a conference? The Creator tab lets you generate, style, and validate QR codes and barcodes offline in seconds.
Can the default iPhone Camera scan UPC or EAN product barcodes?
No. Apple's Camera app and Control Center Code Scanner only recognize 2D codes like QR codes and App Clips. To scan 1D barcodes such as UPC-A, UPC-E, EAN-13, EAN-8, ISBN, Code 128, Code 39, or ITF, you need a dedicated barcode scanner like QR Code Reader & Generator.
Does the iPhone Camera keep a history of scanned QR codes?
No. Once you dismiss the yellow link pill in Apple's Camera app—or close the Control Center Code Scanner—the scan is gone. QR Code Reader & Generator automatically saves every scanned and created code in a searchable local history.
