Verdict
The clearest difference is price: RC at Free against AI Ductulator's $3.99. RC also leads on rating (5.0 vs 3.9) and update cadence (fortnightly vs every 52 months). AI Ductulator's advantage is chart position (#140 vs unranked) and ratings volume (9 vs 1). On ads, in-app purchases and device support there is nothing between them.
