# Qmath vs SpectrumShift

Qmath and SpectrumShift 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. Neither carries in-app purchases, so what you see is what you pay.
