Verdict
The clearest difference is in-app purchases: Rainbow Groupies at none against Ring Stack's 1. Rainbow Groupies also leads on ads (none vs shown) and update cadence (every 5 days vs every 5 weeks). Ring Stack's advantage is ratings volume (18 vs 3) and iOS requirement (12.0 vs 17.0). On price, rating and device support there is nothing between them.
