Verdict
The clearest difference is price: AI Security at Free against ScratchQ's $7.99. AI Security also leads on update cadence (every 3 weeks vs every 22 months) and ratings volume (9.6K vs 1). ScratchQ's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 10). On ads, device support and iOS requirement there is nothing between them.
