# Function Health vs Evolve

The clearest difference is rating: Function Health at 4.9 against Evolve's 4.0. Function Health also leads on ratings volume (25K vs 1) and iOS requirement (16.4 vs 26.0). Evolve's advantage is review sentiment (100% vs 62%) and monetization model (free vs subscription). On price, update cadence, 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.

Function Health holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Function Health has 25K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 62% of Function Health's written reviews are positive against 100% of Evolve's, so the app with the better star average is not the one people write more warmly about.

Function Health ships an update weekly, Evolve every 8 days. The most recent releases landed on October 26, 2026 and September 29, 2026 respectively.
