# どーれかな？（数の理解版） vs 時計を学ぼう

どーれかな？（数の理解版） and 時計を学ぼう 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.
