Verdict

The call

The clearest difference is rating: YAHAHA at 3.6 against Rium's 2.9. YAHAHA also leads on ratings volume (64 vs 8) and iOS requirement (11.0 vs 14.0). Rium's advantage is update cadence (every 9 days vs every 3 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.
