# 21 Card Counter vs Card Grader Pro

The clearest difference is review sentiment: 21 Card Counter at 100% against Card Grader Pro's 56%. 21 Card Counter also leads on in-app purchases (none vs 9) and iOS requirement (13.0 vs 15.5). Card Grader Pro's advantage is rating (4.7 vs 3.7) and ratings volume (5K vs 3). On price, ads and device support there is nothing between them.

Both are free to download. Card Grader Pro sells 9 in-app purchases, starting at $4.99 per month. 21 Card Counter asks for nothing beyond the download.

Card Grader Pro holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Card Grader Pro has 5K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of 21 Card Counter's written reviews are positive against 56% of Card Grader Pro's, so the app with the better star average is not the one people write more warmly about.

21 Card Counter ships an update fortnightly, Card Grader Pro every 4 days. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
