# Derive vs Gradient

The clearest difference is iOS requirement: Derive at 15.0 against Gradient's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Derive sells 7 in-app purchases, starting at $8.99 per month and Gradient sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
