# AI Why? vs Why

The clearest difference is iOS requirement: AI Why? at 13.0 against Why's 15.1. On price and in-app purchases there is nothing between them.

Both are free to download. AI Why? sells 1 in-app purchase, starting at $2.00 per month and Why sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
