# Image Stack vs WhatIf AI

The clearest difference is iOS requirement: WhatIf AI at 15.0 against Image Stack's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Image Stack sells 1 one-off in-app purchase and WhatIf AI sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
