# Card Centering Calculator vs MintCollect

The clearest difference is rating: Card Centering Calculator at 4.7 against MintCollect's 3.9. Card Centering Calculator also leads on ratings volume (2.6K vs 47). MintCollect's advantage is update cadence (weekly vs monthly) and monetization model (ad-supported vs free with in-app purchases). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Card Centering Calculator sells 5 one-off in-app purchases and MintCollect sells 9 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Card Centering Calculator holds the better App Store score, 4.7 against 3.9.
