Verdict
The clearest difference is in-app purchases: Lung Fu at none against Coherence's 6. Lung Fu also leads on rating (5.0 vs 4.8) and review sentiment (100% vs 85%). Coherence's advantage is ratings volume (642 vs 9) and update cadence (every 4 days vs fortnightly). On price and ads there is nothing between them.
