# Level Tool vs Proof Vault Docs

Level Tool and Proof Vault Docs 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. Level Tool sells 4 in-app purchases, starting at $5.99 per 7 days and Proof Vault Docs sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
