# Blackjack 21 vs Blackjack Trainer

The clearest difference is review sentiment: Blackjack Trainer at 100% against Blackjack 21's 55%. Blackjack Trainer also leads on rating (5.0 vs 4.7). Blackjack 21's advantage is ratings volume (5.7K vs 1) and chart position (#169 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Blackjack 21 sells 9 in-app purchases, starting at $7.99 per month and Blackjack Trainer sells 6 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Blackjack Trainer holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Blackjack 21 has 5.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 55% of Blackjack 21's written reviews are positive against 100% of Blackjack Trainer's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
