How does it work? DO you trust its accuracy?
Not at all. It works by displaying a chart that has two humps every day. The chart looks the same every day whether you eat nothing or whether you pig out on carbs. It appears to just be faking it.
Every youtube reviewer of every glucose watch came to the same conclusion.
But I continue to hear that Apple is working on one. The theory is that the watch can sense molecules in your sweat.
