Verdict

The call

The clearest difference is update cadence: NemOZ at every 3 weeks against Sky Castle's every 3 months. NemOZ also leads on review sentiment (100% vs 83%). Sky Castle's advantage is ratings volume (27 vs 4) and iOS requirement (11.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.
