# Fuzz Droid vs iStem

The clearest difference is iOS requirement: Fuzz Droid at 14.0 against iStem's 16.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Fuzz Droid sells 2 one-off in-app purchases and iStem sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
