# Fast36 vs Intermittent Fasting

Fast36 and Intermittent Fasting are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support 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. Fast36 sells 2 in-app purchases, starting at $14.99 per month and Intermittent Fasting sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
