Verdict
The clearest difference is rating: Roman Dates at 4.8 against Skin Motion's 3.2. Roman Dates also leads on ads (none vs shown) and review sentiment (69% vs 50%). Skin Motion's advantage is in-app purchases (none vs 3) and update cadence (every 3 weeks vs every 4 months). On price, monetization model, device support and iOS requirement there is nothing between them.
