# S vs KnowYouth

The clearest difference is ads: KnowYouth at none against S's shown. S's advantage is iOS requirement (12.2 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. S sells 6 one-off in-app purchases and KnowYouth sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
