Verdict
Function Health and SoFit Pro both sit at 4.9 stars, but that hides the real split: 100% of SoFit Pro's written reviews are positive against 62% of Function Health's. SoFit Pro also leads on device support (4 vs 1). Function Health's advantage is update cadence (weekly vs every 2 months) and ratings volume (25K vs 11). On price, rating, ads and in-app purchases there is nothing between them.
