The clearest difference is in-app purchases: Double Down at none against Blackjack ∙'s 11. Double Down also leads on ads (none vs shown) and update cadence (every 8 days vs every 3 weeks). Blackjack ∙'s advantage is ratings volume (49K vs 4) and chart position (#144 vs unranked). On price, rating and device support there is nothing between them.
