Disclosure: We make Barcode & QR Scanner, one of the apps compared below. We've tried to keep this comparison neutral and factual, and we've linked what we could verify.
Last checked: October 2026.
Short answer: for occasional scanning you do not need an app at all — the built-in camera handles it on both platforms. An app is worth installing if you need scan history, batch scanning, or code generation. Look for offline operation, no forced account, and a URL preview before opening any link.
Our own Barcode & QR Scanner app follows that checklist — instant scanning plus a built-in generator. For the basics of scanning itself, see how to scan a QR code, and for decoding a code already saved as an image, see how to scan a QR code from an image.
Criteria We Compared On
| Criterion | Why it matters |
|---|---|
| Speed | Scans in under a second |
| Privacy | No scan data sent to servers |
| History | Saves scans for later |
| Generation | Creates QR codes as well as reading them |
| Offline | Works without an internet connection |
| Format support | Handles barcode types, not just QR |

Why Privacy Matters for QR Scanning
QR codes can contain sensitive information:
- Login credentials and authentication tokens
- Wi-Fi passwords shared via QR
- Personal contact information (vCards)
- Payment details and transaction data
Choose a scanner that processes everything locally on your device and doesn't upload scan data to servers.
The Bottom Line
