Verdict
The clearest difference is price: QRZing at Free against Konvert's $1.99. QRZing also leads on update cadence (every 2 days vs monthly) and review sentiment (100% vs 79%). Konvert's advantage is ratings volume (364 vs 2). On ads, in-app purchases, monetization model and device support there is nothing between them.
