# Deep Core vs Willow

The clearest difference is ads: Deep Core at none against Willow's shown. Willow's advantage is iOS requirement (15.1 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Deep Core sells 7 one-off in-app purchases and Willow sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
