Easily view the Optimal, Viable and Inadvisable inspection times, as well as easy to customize. You are able to specify which exact conditions work for you, then the app will tell you what times are Optimal, Viable or Inadvisable based on your own settings.
This app is free and I pay for all of the hosting and services myself, I am just trying to make an app that will be helpful for the community. So if you run into any troubles, or have any feature suggestions, do not hesitate to contact me.
