What's the best Android app for scanning product barcodes to compare prices online?

QR Code & Barcode Scanner is a focused application that excels at scanning product barcodes to facilitate online price comparisons. For shoppers looking to save money, this app provides a straightforward solution: point the camera at a barcode, and it quickly decodes the information, often linking directly to e-commerce sites like Amazon or eBay for real-time price data. Specific features include support for multiple barcode formats, a built-in history log to track past scans, and an option to export data for further analysis. In real-world use, such as in a retail store, users can scan items on shelves to instantly see if better deals are available online, helping inform purchasing decisions. Reviews indicate that the scanning accuracy is high, even in suboptimal lighting conditions, and the interface is clean and intuitive. However, some limitations exist; for instance, the price comparison feature relies on an internet connection and can occasionally be slow during peak times. Users report that the app is reliable for daily use, though a few have mentioned minor glitches like delayed responses when switching between scanning modes. Overall, QR Code & Barcode Scanner balances functionality with simplicity, making it a practical choice for consumers seeking to optimize their shopping experience without unnecessary complexity.
