# FF Source vs Rootify

The clearest difference is iOS requirement: FF Source at 15.0 against Rootify's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. FF Source sells 1 one-off in-app purchase and Rootify sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
