The clearest difference is rating: JSON Navigator at 5.0 against Smart NFC's 4.5. JSON Navigator also leads on review sentiment (67% vs 48%) and price ($0.99 vs $1.99). Smart NFC's advantage is ratings volume (92 vs 2). On update cadence, ads, in-app purchases and chart position there is nothing between them.

JSON Navigator holds the better App Store score, 5.0 against 4.5.
