# Fast & Slim vs Intermittent Fasting

Fast & Slim and Intermittent Fasting are too close to call on the numbers: across 3 compared parameters — price, in-app purchases and iOS requirement among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Fast & Slim sells 1 one-off in-app purchase and Intermittent Fasting sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
