Verdict

The call

The clearest difference is ads: Blackjack Trainer at none against Blackjack 21!'s shown. Blackjack Trainer also leads on update cadence (every 3 days vs every 3 months) and rating (4.9 vs 4.6). Blackjack 21!'s advantage is ratings volume (6.1K vs 8) and iOS requirement (15.0 vs 17.6). On price, in-app purchases, monetization model and device support there is nothing between them.
