# Card Grader Pro vs OilTrax

The clearest difference is in-app purchases: OilTrax at none against Card Grader Pro's 9. OilTrax also leads on rating (5.0 vs 4.7). Card Grader Pro's advantage is ratings volume (5K vs 1) and iOS requirement (15.5 vs 17.0). 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. OilTrax asks for nothing beyond the download.

OilTrax 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 5K ratings behind it against 1, so its average is the more settled of the two.
