 This is Elizabeth Lopato. I'm reporting for The Verge on the HealB GoB. Apparently has three sensors. There's an accelerometer. There's a pulse sensor. And there is a sensor that is essentially meant to detect the amount of water that is being extruded from your cells. Like basically the amount of water that's coming out of your cell. The idea is this is supposed to be a proxy measure for blood sugar and using that you can sort of get a sense of calorie count. My understanding is that there have been studies that have been performed on how accurate this is for calorie counts. They're not peer reviewed studies that are published in a journal. They are published on the company's website. And this is essentially 85% accurate for calorie counts as the result. So the app on the phone measures a couple of things. It measures calories. It measures sleep. It measures stress. It measures hydration. This was an Indiegogo project. The folks who backed this will be getting their units at the end of the month.
