# PDF Unlock vs PDF Lite

PDF Unlock and PDF Lite are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases 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. PDF Unlock sells 6 in-app purchases, starting at $0.99 per month and PDF Lite sells 4 in-app purchases, starting at $15.99 per year. Whichever you choose, the download price is not the number that matters.
