Developer does not understand how a barometer works

Useless app. No ability to correct for standard sea-level pressure. I live at 6000 feet. Barometer always shows 0!
Amazing that you could produce an app with absolutely no understanding of the concept.
Im a commercial pilot and thought this would be interesting. If enough people waste their 99 cents, maybe it will pay for a high school physics class for the developer.
