# GradeKey vs Grade Calculator

GradeKey and Grade Calculator 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. GradeKey sells 1 one-off in-app purchase and Grade Calculator sells 2 in-app purchases, starting at $4.99 per year. Whichever you choose, the download price is not the number that matters.
