# FastFlow vs FastingKit

The clearest difference is ads: FastingKit at none against FastFlow's shown. FastingKit also leads on device support (4 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. FastFlow sells 2 in-app purchases, starting at $0.99 per month and FastingKit sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
