# Card Grader Pro vs Centered Cardboard

Card Grader Pro and Centered Cardboard both sit at 4.7 stars, but that hides the real split: 100% of Centered Cardboard's written reviews are positive against 56% of Card Grader Pro's. Card Grader Pro's advantage is ratings volume (5K vs 59) and update cadence (every 4 days vs every 3 weeks). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Card Grader Pro sells 9 in-app purchases, starting at $4.99 per month and Centered Cardboard sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Card Grader Pro against 4.9 for Centered Cardboard. That said, the two scores are not equally well evidenced: Card Grader Pro has 5K ratings behind it against 59, so its average is the more settled of the two. Written reviews are what separate them: 56% of Card Grader Pro's written reviews are positive against 100% of Centered Cardboard's.

Card Grader Pro ships an update every 4 days, Centered Cardboard every 3 weeks. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
