Observation by Henry Lahore, founder of VitaminDWiki

I have been tracking simple Vitamin D testers for over 4 years
Many candidate designs have come and gone.
It appears to be a very difficult problem
The only group which I am aware of which has a chance at getting this prize is Nanospeed
My review of their development is Low-cost Vitamin D testers (about 13 dollars in quantity) – Feb 2018
They currrently have a low cost tester which requires an expensive readout device.
   Would be OK for use iin pharmacies, but not in the home
It appears feasible to use a smartphone(with camera) as no-cost readout device
I am sending them a link to this prize
