A couple of weeks ago, I asked what new functions we could add to our smartphones. Kontra has a suggestion:
Which would you prefer to have in iPhone 13 Pro cameras?
a) 4X telephoto
b) Spectrometer (for instant display of body fat, freshness/nutritional value of food, skin moisture, alcohol % in drinks, etc)

A spectrometer would be nice. If nothing else, it would finally satisfy the yearning that many of us have for a real tricorder.
