Verdict
The clearest difference is rating: OMEGA Scan at 5.0 against Structure's 3.1. OMEGA Scan also leads on iOS requirement (11.0 vs 13.0). Structure's advantage is update cadence (every 2 months vs every 7 months) and ratings volume (15 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
