The application is very useful to Civil Engineers, Architects, Surveyors, and those interested in measuring a surface area or converting its coordinates to UTM EGSA87. This tool enables users to: 1. Convert the coordinates (x,y) to UTM EGSA87 Datum 2. Calculate the area of a polygon in square meters (m2) 3. Send the above measurements by e-mail in [dxf] file format. The dxf file can be opened in a MAC or a PC by any drawing application like Autocad. 4. Send measurements by e-mail in [kml] file format. The kml file can be opened in a MAC or a PC or iPhone by GoogleEarth application. 5. Send measurements by e-mail in [TXT] file format. The text file contains coordinates either in EGSA87 Datum or Latitude and Longitude in decimal degrees or UTM coordinates. The measurements mentioned above can be provided not only by placing the iPhone in each border of a surface area, but also from distance (when users are on their bed or their sofa). Users may also have their final measurements by entering the coordinates either in EGSA87 Datum or Latitude and Longitude in decimal degrees.

Verdict
The clearest difference is price: AutoGPS at Free against Topography's $3.99. AutoGPS also leads on iOS requirement (13.0 vs 16.1). Topography's advantage is update cadence (every 2 months vs every 4 months). On ads, in-app purchases and device support there is nothing between them.
