“Vessyl can tell the difference between strong and weak coffee, Lee says, noting caffeine disparities. It can even measure the sugar, protein, calories, fat, and caffeine inside any beverage you pour into it, mass-produced or homemade. As you go about your day, the device tracks how much you’re drinking, and when you tilt Vessyl to its back, it displays a bright blue line that rises and falls to indicate your hydration level. Even sleek apps like Up Coffee, which tracks your caffeine consumption, require you to input your consumption manually drink by drink. The big idea behind Vessyl is to provide transparency, automatically, about how terrible most of our drinking habits are.”
