# Whatsify vs KnittingConverter

The clearest difference is iOS requirement: Whatsify at 12.0 against KnittingConverter's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

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