According to their video, https://www.youtube.com/watch?..., one of the uses is to detect the sweetness of certain fruits. The video shows them scanning an apple to determine the level of sugar. This would be useful if you are in the grocery store and want to pick the sweetest from among apples, peaches, etc. Do you think their tool is sufficient for this purpose? What about fruits with skins you do not eat like watermelon? Or, what about fruits like pomegranates? If their tool would not be sufficient, is there a handheld spectrometer that could be used?

I have a theory that it's impossible to prove anything, but I can't prove it.
