# Any Formula vs RF Toolbox

The clearest difference is iOS requirement: RF Toolbox at 13.0 against Any Formula's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Any Formula sells 1 one-off in-app purchase and RF Toolbox sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
