Altitude App

This altimeter delivers the altitude of your current position either from the device (GPS) or from the ASTER digital elevation model (with a horizontal accuracy of 30m).

Depending on your current position and your device one of the two methods is more correct. Using GPS on the device is known for a large error in the altitude for difficult receiver conditions it's not available for network based positioning at all.

Therefore this altimeter works on iPods and iPhones without a GPS sensor.

More features:
- switch between metric and feet units
- set an optional target altitude
- switch between Device, ASTER and combined altitude
- support for the iPhone 6 and 6+
- support for the iPad multitasking (split view..)
