# Refractive vs Jones polynomial

The clearest difference is iOS requirement: Refractive at 10 against Jones polynomial's 16.6. On price, ads, in-app purchases and device support there is nothing between them.

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