# Spren Body Composition Scanner vs MomKnows!

Spren Body Composition Scanner and MomKnows! 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. Spren Body Composition Scanner sells 14 in-app purchases, starting at $10.49 per month and MomKnows! sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
