# Math vs 9

The clearest difference is in-app purchases: Math at none against 9's 1. Math also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 9 sells 1 one-off in-app purchase. Math asks for nothing beyond the download.
