# Kauri vs Flow Study

The clearest difference is iOS requirement: Kauri at 13.0 against Flow Study's 15.4. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Kauri sells 8 in-app purchases, starting at $22.99 per month and Flow Study sells 6 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
