# 21 Pro vs Card Counter

The clearest difference is price: 21 Pro at Free against Card Counter's $2.99. 21 Pro also leads on update cadence (every 2 weeks vs every 4 months) and ratings volume (677 vs 113). Card Counter's advantage is in-app purchases (none vs 7) and review sentiment (88% vs 72%). On rating, ads and device support there is nothing between them.

21 Pro is free to download; Card Counter costs $2.99 up front. 21 Pro sells 7 one-off in-app purchases. Card Counter asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for 21 Pro against 4.7 for Card Counter. That said, the two scores are not equally well evidenced: 21 Pro has 677 ratings behind it against 113, so its average is the more settled of the two. Written reviews are what separate them: 72% of 21 Pro's written reviews are positive against 88% of Card Counter's.

21 Pro ships an update every 2 weeks, Card Counter every 4 months. Both last shipped on November 6, 2026.
