What should the best health data app include?

Passive data capture, explainable insights, personal baselines, privacy controls, confidence labels and clear medical boundaries.

Is daygauge a medical app?

No. daygauge is personal lifestyle analytics, not diagnosis, treatment or disease-risk prediction.

Why are evidence important?

Evidence keep scores explainable by showing the signal, baseline, source, confidence and score impact.

Buying guide

The best health data app is the one that explains what changed and why it matters.

daygauge reads Apple Health sleep, movement and daily patterns, then shows what helped, what held the day back and what to try next.

Guide

What a good health data app should do

It should connect sleep, movement, recovery, places, habits and optional wearables into a clear daily and weekly story.

Charts are not enough. Users need evidence: observed value, baseline, source, confidence and score impact.

Guide

Why daygauge is different

daygauge is not trying to be a medical app, a running app or a wearable clone.

The product thesis is lifestyle intelligence: understand how you live, then run careful personal experiments.

Guide

What should be Pro

Pro is the attribution layer: what helped, what cost you, what repeated, and what to test next.

That is why Daily Quest, full evidence, experiments, weekly recap and local rank belong behind Pro.

Evaluation checklist

What most health dashboards still miss.

The next step after charts is attribution. A useful health data app should answer: did this change happen on similar weekdays, did it repeat, what source saw it, how confident is the app, and what is the smallest safe experiment?

Baseline: compares you with your own recent pattern before population context.
Evidence: shows observed value, baseline value, confidence and score impact.
Experiments: lets users log one change such as caffeine cutoff, no-vape day, post-meal walk or creatine day.
Privacy: keeps sensitive sources opt-in and out of leaderboards.
Boundaries: uses research context without disease-risk prediction or treatment advice.

daygauge example

“On logged post-meal walk days, evening energy notes improved and sleep timing stayed within baseline. Medium confidence. Repeat three more days before treating it as a pattern.”

Research context

Sources daygauge can cite without overclaiming.

These sources inform product wording and evidence labels. They should not be turned into personal diagnosis, treatment or disease-risk prediction.

Research context only. daygauge does not diagnose, treat, prevent or predict disease risk. Personal medical concerns belong with a qualified clinician.
