# Lucrux vs Kaddy

The clearest difference is iOS requirement: Kaddy at 15.0 against Lucrux's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Lucrux sells 2 in-app purchases, starting at $14.99 per month and Kaddy sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
