Very useful – Barometer & Altimeter Pro Review
Barometer is the most basic instrument used in weather forecasting - I always wanted one that I could hang on the wall to monitor weather; now I have one in my pocket with this app on iPhone. The app even plots pressure changes over time. The Pro version allows export of this trend data to CSV file; that makes this app a serious tool for more sophisticated work. Very useful.
