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.
- switch between metric and feet units
- set an optional target altitude
- switch between Device, ASTER and combined altitude
