# QR Code Scanner vs Calculator+ Pro & Math Solver

QR Code Scanner and Calculator+ Pro & Math Solver 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. Neither carries in-app purchases, so what you see is what you pay.
