# Formulize vs Stress Matrix

Formulize and Stress Matrix 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. Formulize sells 1 one-off in-app purchase and Stress Matrix sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
