Looking for someone to code an app in Unreal that we can port to Android & iOs

We need a freelancer to code an app. We have a decision tree and block diagram available as a basis for quotations.

The app is essentially a calculator that would benefit from its results being represented as a static image(s) whose
appearance would change based on the calculation result.

Here are the variables to consider in the calculations:

  1. Ambient Light: collected by an off-the-shelf light meter app for Android or iOs and expressed in lux

  2. Source Light: specified and expressed in Lumens

  3. Area to be illuminated by the Source light

  4. Reflectivity Ratio of the area illuminated by the Source light

We would like to see the results of the above calculations expressed in several different ways:

  1. As a selection from a 10-20 cell lookup table of Reflectivity Ratio options

  2. As a selection from a 100-200 cell lookup table of Source Light options

  3. Relatively photo realistic renderings of five (or more) static images and, potentially, some video clips based, on (1 x 2)
