# Card Grader Pro vs CenterMint

The clearest difference is ads: Card Grader Pro at none against CenterMint's shown. Card Grader Pro also leads on ratings volume (4.9K vs 1) and iOS requirement (15.5 vs 17.0). CenterMint's advantage is rating (5.0 vs 4.7). On price, update cadence, in-app purchases and monetization model 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 CenterMint sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

CenterMint holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Card Grader Pro has 4.9K ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
