Altitude Pro

This altimeter shows the altitude of your current position (from GPS and NASA).

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 devices without a GPS sensor.

It's the perfect app for tracking your height on all outdoor activities e.g. hiking, biking or while in flight.

More features:

- switch between metric and feet units

- set an optional target altitude

- switch between Device, ASTER and combined altitude
