Real Altimeter Plus

Turn your phone into a real working aircraft altimeter.

Features:
* Touch and drag to set reference pressure.
* Set reference pressure based on nearby METAR stations.
* Altitude in metres and feet.
* Pressure in hPa, mbar, or inHg.
* Easy to use.

This app is only available for devices with a built-in barometric sensor.

DISCLAIMER:
This is not an approved aircraft instrument. This software program can not take the place of an approved and properly calibrated aircraft altimeter. For education purposes only.

IMPORTANT NOTE:
This altimeter will not work inside a pressurised cabin, like those found on an airliner: it will show cabin altitude, not actual altitude.
