Displays a map of what you point your device at twice using triangulation. You move between 2 locations ('A' & 'B') and it will calculate the 3rd ('C') based upon the angles and GPS coordinates of the previous 2.
Wuts @ also gives you: Map of C. - use zoom, layers, etc from Google maps. Hit back to return to Wuts @ GPS coordinates of C. Distance in Miles, Feet and Kilometers. Distance from A to B, A to C, B to C, and your total path from A. 3 different algorithms to compute distance. Change background color. Turn on/off sound (when GPS receives new signal). When A & B coordinates don't point to any C. - Get distance A to B. Input your own coordinates and save them. Has a database of some famous landmarks. Find out how far any of these points are from you.
Note: This program will only bring up a map as accurate as your GPS and compass are. Move your device in a figure 8 pattern to get a more accurate azimuth before you hit 'A' and 'B'.
The declination or magnetic deviation has been set to 13 by default, which is the Las Vegas, Nevada area. Consult an aviation map, Google, or calibrate to find the declination for your area.
To calibrate, go near an object which you can see from a distance south. Hit 'A', then go south a ways and hit 'calibrate' under the 'Adj' menu. You will see a number in feet. Move until it reads '0'. Point your phone grid north to the 'A' object and then hit 'set'.
