# Fast vs Simple Fasting

The clearest difference is ads: Fast at none against Simple Fasting's shown. Simple Fasting's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.4). On price and in-app purchases there is nothing between them.

Both are free to download. Fast sells 1 in-app purchase, starting at $0.99 per month and Simple Fasting sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
