It has full trip functionality. iSpeed will work for either your car, boat, bike, or while you walk. Features Include: - The Speed View shows your speed, heading, course, altitude, odometer, trip and drive details. It also shows the current and next 24 hour weather conditions. Your current GPS accuracy is displayed at the bottom. - The Data View displays the raw GPS location, speed, heading, trip data, and current battery status. - The Settings View allows you to set the unit of measurement and compass winds. --- Notes: --- Works on the iPhone running iOS 14.0 or later. The weather requires a data connection to display information. Continued use of GPS running in the background can dramatically decrease battery life. Have a safe trip!

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.
