# Duo Math Games, Multiplication vs 1×1 Master

Duo Math Games, Multiplication and 1×1 Master 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. Duo Math Games, Multiplication sells 5 in-app purchases, starting at $4.99 per 7 days and 1×1 Master sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
