Health optimisation topics daygauge can explain safely.
These guides are built for search and user education. They separate measurable lifestyle signals from topics that should stay as research context only.
High-interest topics, with useful answers and product boundaries.
Each guide is written around the question a user is likely to search, then translated into what daygauge could measure, explain or refuse to infer. The goal is to make the marketing pages useful before someone ever installs the app.
That matters commercially: the promise is not another wellness blog. It is a preview of the insight engine users would pay for: evidence, baselines, confidence, research context and a hard line against fake medical certainty.
