Verdict

The call

The clearest difference is ads: Blackjack at none against Sport Star's shown. Blackjack also leads on review sentiment (80% vs 58%). Sport Star's advantage is ratings volume (801 vs 15) and update cadence (every 4 days vs every 2 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Blackjack sells 6 in-app purchases, starting at $2.99 per 7 days and Sport Star sells 16 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.6 for Blackjack against 4.5 for Sport Star. That said, the two scores are not equally well evidenced: Sport Star has 801 ratings behind it against 15, so its average is the more settled of the two. Written reviews are what separate them: 80% of Blackjack's written reviews are positive against 58% of Sport Star's.

UpkeepUpdate frequency

Blackjack ships an update every 2 weeks, Sport Star every 4 days. The most recent releases landed on September 15, 2026 and September 24, 2026 respectively.
