# Water Fasting vs FastFlow

The clearest difference is iOS requirement: FastFlow at 16.4 against Water Fasting's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Water Fasting sells 2 in-app purchases, starting at $9.99 per month and FastFlow sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
