Verdict
The clearest difference is in-app purchases: Rolling Sky Ballz at none against Stack's 18. Rolling Sky Ballz also leads on iOS requirement (11.0 vs 13.0). Stack's advantage is ratings volume (59K vs 74) and update cadence (every 10 days vs every 2 months). On price, rating, review sentiment and ads there is nothing between them.
