Barometric Altimeter

Barometric Altimeter is based on the new barometer in iPhone 6, iPhone 6 Plus and iPad Air 2.
On other devices the app shows your GPS altitude.

You can either use automatic calibration (best in most cases) or manual calibration.
For manual calibration use the following options:
- enter your current altitude
- use altitude-information from your GPS device
- enter current sea-level air-pressure
- use local weather data from the internet for your current position

You can choose between meter and feet for altitude display.
