# DR vs Nodes AI

The clearest difference is ads: Nodes AI at none against DR's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. DR sells 1 one-off in-app purchase and Nodes AI sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
