# Engineering Materials for Exam vs Mechanical Formula

Engineering Materials for Exam and Mechanical Formula 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. Engineering Materials for Exam sells 10 one-off in-app purchases and Mechanical Formula sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
