# Knot 3D vs FoundKey

The clearest difference is ads: FoundKey at none against Knot 3D's shown. Knot 3D's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.6). On price and in-app purchases there is nothing between them.

Both are free to download. Knot 3D sells 2 one-off in-app purchases and FoundKey sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
