The best thing is to cross-reference with the AGE meter that people like Aaron King use

Iām using Apple products and may be missing something but reading the description of the Galaxy Watch 7, I donāt know how it could infer a proxy for AGE. The āAIā function is not explained technically in the literature I reviewed. It would likely need to be an off-watch cloud function based on trend analyses of the small number of metrics the sensor can capture.

I couldnāt find the price on this AGE Reader from Diagnoptics. Guess Iād have to request a quote.
The watch itself isnāt that expensive. You can always return it back in 30 days if you donāt like itā¦

It breaks down separate sleeps/naps, but it drastically underestimates my REM sleep (Iāve been dreaming very intensely the last 2 weeks)

Does this measure smg like fructosamine? Iāve always had semi-high fructosamine levels 
Maybe Iām going to try heroic doses of carnosine+taurine+metformin at some pointā¦
This is a really cool feature that could be very useful if it were accurate enough, which I doubt. I donāt see any information on which specific fluorescent AGEs it supposedly detects and exactly where (just in the skin or also in the blood?) and how accurately it detects changes in response to interventions that lower AGE production. Also how does it compare to the AGE reader?

Yes, they need to provide accuracy data and comparisons to the general population by chronological age.
