# PlumbCalc Pro vs PipeFall

PlumbCalc Pro and PipeFall 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. PlumbCalc Pro sells 2 in-app purchases, starting at $9.99 per month and PipeFall sells 4 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
