As you can see I decided to error in the warmer side (below 6500k) but of course with more time I could get better results bit I don't think it's worth trying to hard with this app because it's not accurate anyway. Use your eyes!
I learned about this app from @dirtgarry and he made a video proving the accuracy of this app with a 6500k light source. Here's his video https://youtu.be/-jcTKVMVoa4
