# Artist Tools vs DoubleCheck

The clearest difference is iOS requirement: Artist Tools at 16.0 against DoubleCheck's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Artist Tools sells 4 in-app purchases, starting at $1.99 per month and DoubleCheck sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
