# 75 Day Challenge vs Protocol 75

75 Day Challenge and Protocol 75 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. 75 Day Challenge sells 25 in-app purchases, starting at $2.99 per 7 days and Protocol 75 sells 1 in-app purchase, starting at $4.99 per 3 months. Whichever you choose, the download price is not the number that matters.
