# Lock vs why?

The clearest difference is iOS requirement: Lock at 13.0 against why?'s 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Lock sells 2 in-app purchases, starting at $0.99 per 3 months and why? sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
