Verdict

The call

The clearest difference is in-app purchases: Rainbow Groupies at none against Brain Test's 8. Rainbow Groupies also leads on ads (none vs shown) and update cadence (every 5 days vs monthly). Brain Test's advantage is ratings volume (6.5K vs 3) and iOS requirement (12.5 vs 17.0). On price and device support there is nothing between them.
