Point your camera at a hill, village, lake or landmark on the horizon and Horizon Explorer will tell you what you're aiming at. Name, distance, altitude and map of the pointed at landmark will be displayed. Wikipedia markers for points of interest are overlaid on the view with Augmented Reality.
Fly up high and see the terrain laid out below you to see what is over the hills around you, and get the lay of the land, then see the scale-model 3D map that you can walk around to find out what's behind hills, or explore the terrain for anywhere in the world.
Horizon Explorer works worldwide, but works best on top of a hill with an unobstructed view of your surroundings. You can drag the horizon line with your finger to line up with the camera if the automatic tracking is not working very well. Or try waving your phone around in the air in a figure 8, then pressing "autoalign" to calibrate the compass.
