# Function Health vs Superpower

The clearest difference is monetization model: Superpower at free against Function Health's subscription. Superpower also leads on review sentiment (86% vs 62%). Function Health's advantage is ratings volume (25K vs 1.5K) and update cadence (weekly vs fortnightly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.9 for Function Health against 4.9 for Superpower. That said, the two scores are not equally well evidenced: Function Health has 25K ratings behind it against 1.5K, so its average is the more settled of the two. Written reviews are what separate them: 62% of Function Health's written reviews are positive against 86% of Superpower's.

Function Health ships an update weekly, Superpower fortnightly. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
