With any (two inputs), the app will calculate all of ramp's information accurately: - Slope (incline). - Run (horizontal travel). - Ramp Length. - Rise (Height). - Slope (Percentage, Ratio & Angle). Possible scenarios of calculation: by adding any of the following inputs, the app shall calculates the rest: - Run & Rise. - Run & Length. - Rise & Length. - (Slope percentage, Slope Ratio or Slope Angle) with any of (Rise, Length or Run). The App has a built-in tool to measure the slope of an existing ramp or a surface, by using the capabilities of your iPhone / iPad device. * Remember to use a proper protection case though, to prevent your device from scratches and to give it a perfect flat shape, for better accuracy.
