Verdict
The clearest difference is rating: Knots 3D at 4.9 against AFV Recognition's 4.4. Knots 3D also leads on review sentiment (98% vs 65%) and update cadence (every 2 weeks vs every 4 months). AFV Recognition's advantage is iOS requirement (12.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.
