Barometric Altimeter

This altimeter models a real aviation altimeter by using your device's barometer and allowing calibration of altitude based on air pressure at sea level (QNH) and the current air temperature. If a network connection is available, the app can fetch the closest weather station data automatically and auto-calibrate every 10 minutes or as you travel. Manual calibration is easily accomplished by sliding up and down on "Kollsman"window or on the right side of the altimeter. Features : - 2 hand analog altimeter with smooth animations. - Kollsman window for manual calibration. - Analog and digital display options. - Filtered pressure data for more stable readings and less jumpy altitudes. - User preferences and calibrations are saved upon exit. - Auto calibration via the closest Metar station (sets sea level pressure and current temperature) when an Internet connection is present - Auto calibrates every ten minutes to save battery life - Easy manual calibration by sliding up/down or via the settings - Imperial and metric support.
