# PowerMath vs GrayMatter

The clearest difference is ads: GrayMatter at none against PowerMath's shown. PowerMath's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price and in-app purchases there is nothing between them.

Both are free to download. PowerMath sells 8 in-app purchases, starting at $1.99 per month and GrayMatter sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
