NOT A FLIGHT INSTRUMENT
NOT FOR NAVIGATION
A bare bones pressure altimeter just like the one in an airplane (except red, for some reason). There are no additional features: if an airplane altimeter doesn't do it, this app won't do it. Unless you count "being red" as a feature.
Uses the pressure sensor in your Android device and the altimeter setting you provide to estimate your altitude. Don't have a pressure sensor? In that case, it pretends you're at sea level. Just to make it clear: this app won't show your altitude unless your device has a pressure sensor inside.
New to altimetry? Check Wikipedia to learn more about altimeter settings (http://en.wikipedia.org/wiki/Altimeter). Then check your nearest, most recent METAR (http://en.wikipedia.org/wiki/METAR) to learn the correct altimeter setting for your area.
Instructions:
Use the volume buttons to change your altimeter setting.
Long-press anywhere to toggle debug information.
Features:
Kalman filter smooths out sensor noise
Requires no special permissions at all

Limitations:
