# Knew vs Math2 A

The clearest difference is ads: Knew at none against Math2 A's shown. Knew also leads on iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Knew sells 5 one-off in-app purchases and Math2 A sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
