# RF Engineer Toolkit vs RF Toolbox

The clearest difference is iOS requirement: RF Toolbox at 13.0 against RF Engineer Toolkit's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. RF Engineer Toolkit sells 3 in-app purchases, starting at $0.99 per month and RF Toolbox sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
