# Auto vs HDRI Studio

The clearest difference is iOS requirement: HDRI Studio at 17.0 against Auto's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Auto sells 1 one-off in-app purchase and HDRI Studio sells 3 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
