# Convert IT vs Concrete Calculator

The clearest difference is ads: Concrete Calculator at none against Convert IT's shown. Convert IT's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18). On price and in-app purchases there is nothing between them.

Both are free to download. Convert IT sells 2 in-app purchases, starting at $0.99 per 7 days and Concrete Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
