# Dr PK Classes vs SKY SPACE

Dr PK Classes and SKY SPACE 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. Dr PK Classes sells 1 one-off in-app purchase and SKY SPACE sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
