Verdict
The clearest difference is in-app purchases: Mamori at none against RT's 5. Mamori also leads on iOS requirement (13.0 vs 26.0). RT's advantage is update cadence (monthly vs every 5 months) and chart position (#200 vs unranked). On price, ads and device support there is nothing between them.
