So we decided to create an application that shows the angle of the car body. With the application you can also specify an approximate angle for roller coaster, descent or slope. Also, there is an altimeter, compass, location data, the ability to intercept the maximum recorded result of slope in all directions and the speedometer for IPad version. Now you are able to use an image of your choice. 1.Clinometer 2.Location 3.Compass 4.Altimeter 5.Speedometer
