Rigorous statistics between local weather and your logged symptoms — with honest uncertainty, not magic.

The problem

Many weather-sensitive people suspect a pattern — headaches before a front, joint pain on damp days — but memory is a poor statistician: it keeps the hits and forgets the misses.

What MeteoHealth does

MeteoHealth correlates local weather with your symptom entries and Apple Health metrics, and shows which associations in your own data look statistically meaningful — and which are probably noise.

How it works

The app pairs your entries with hourly weather — pressure, humidity, temperature, wind — and runs Pearson correlations, ANOVA and FDR correction on your device. Results are shown as associations with confidence levels, never as diagnoses. Detailed correlations are part of Pro.

What it does not do

It does not diagnose anything and does not claim causation: a correlation in your data is an association, not proof that weather caused a symptom. The statistics run on your device — results are not uploaded anywhere.
