What am I seeing?

Solid dots are actual station measurements. Dashed lines between dots connect reported readings; they don't mean pressure was measured at every minute. The dashed portion after the final dot is a provisional weather-model estimate.

Checking model information…

The graph uses at least 0.30 inHg (about 10 hPa) of vertical scale, expanding when needed. This keeps small changes from looking exaggerated. The readings and alert thresholds are unchanged.

Estimates can be wrong or miss brief fluctuations. The app uses National Weather Service station data and Open-Meteo models. Ground-level pressure is modeled only. Not a diagnostic measurement.

ⓘ How these patterns work

Check-ins record when you noticed your balance, not when symptoms first changed. These comparisons can suggest patterns, but cannot establish that pressure caused symptoms.

For useful comparisons, record both steady and unsteady checks during similar activities. Personalized suggestions require repeated check-ins over several weeks and never change notifications without your approval.

Pressure readings come from a reporting weather station. Up to 120 days are saved on this device when the app is opened or refreshed; missing or widely spaced measurements are excluded. Symptom history stays on this device.
