# PRO vs S+K

The clearest difference is review sentiment: S+K at 100% against PRO's 4%. S+K also leads on rating (5.0 vs 1.0) and iOS requirement (12 vs 16.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
