# Centering50 vs Art Official Grading

The clearest difference is ads: Art Official Grading at none against Centering50's shown. Art Official Grading also leads on rating (5.0 vs 4.7). Centering50's advantage is ratings volume (54 vs 3). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Centering50 sells 3 in-app purchases, starting at $4.99 per month and Art Official Grading sells 10 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Art Official Grading holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Centering50 has 54 ratings behind it against 3, so its average is the more settled of the two.
