Millibars running on iPhone and iPad, showing a graph of barometric pressure

Unlike other weather apps, Millibars doesn't just show a forecast. Millibars gives you a history of recent barometric pressure changes in your location so you can understand how your body reacts. You can see 10 days of history and 24 hours of forecast data in one simple graph.

Millibars is currently in development, but you can get an early look by joining the beta test via TestFlight:
