Quick answer: three focused tools — a 48-hour barometric pressure-drop tracker (migraine/joint-pain window), an exact golden-hour/blue-hour solar calculator with drone flight score, and weather-triggered home service alerts. All client-side math; live data where a free keyless source exists.
Migraine risk tracks the rate of pressure fall, not rain. Clinical studies associate migraine onset with drops of ~5–10 hPa within 24 hours below the 1013 hPa baseline. Enter coordinates to pull the next 48h of hourly sea-level pressure from the US National Weather Service (free, keyless, commercial-friendly).
Informational weather tool — not a medical device. If you experience severe symptoms consult a clinician.
Golden hour is when the sun sits between −4° and +6° elevation; blue hour −4° to −6°. The window stretches from ~25 min near the equator to over an hour at high latitudes. Pure solar geometry below — works offline, any date.
