# Oura vs Function Health

Function Health's advantage is review sentiment (62% vs 49%). On price, rating, update cadence and ads 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 Oura against 4.9 for Function Health.
