# QR & Barcode Scan vs Convertology

The clearest difference is rating: QR & Barcode Scan at 4.8 against Convertology's 4.0. QR & Barcode Scan also leads on ratings volume (50 vs 1) and chart position (#90 vs unranked). Convertology's advantage is update cadence (every 6 days vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
