Verdict
The clearest difference is in-app purchases: MIETHKE at none against Spine's 1. MIETHKE also leads on review sentiment (100% vs 75%) and update cadence (every 5 months vs every 26 months). Spine's advantage is ratings volume (59 vs 1). On price, rating and ads there is nothing between them.
