# The ARC Library vs Margin

The ARC Library and Margin 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. The ARC Library sells 4 in-app purchases, starting at $2.99 per month and Margin sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
