Vessyl, a smart cup designed by Yves Behar, is designed to measure and track any drink poured into it in real-time. Using sensors, Vessyl is able to detect drinks that are poured in to it, from water and soda to homemade smoothies, alcoholic beverages, coffee, tea, and more.
When a drink is poured into Vessyl, an accompanying iPhone app displays all of the relevant nutritional information about the drink. Vessyl is able to track many pre-bottled drinks, but it is also able to determine the nutritional content of handmade beverages, such as smoothies or mixed drinks. The Verge was able to test Vessyl and has a detailed piece on the cup, including notes on its accuracy.
Let's cut to the chase: while I only had an hour with a Vessyl prototype, I tried nearly a dozen beverages in it -- and it successfully identified all of them. Within 10 seconds, the device, which currently resembles more of a Thermos than a finished product, recognized Crush orange soda, Vitamin Water XXX, Tropicana orange juice, Gatorade Cool Blue, plain-old water, and a few other beverages, all by name. Yes, this cup knows the difference between Gatorade Cool Blue and Glacier Freeze.
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.
Along with displaying nutritional information, Vessyl also keeps track of what a user drinks during the day, tallying statistics like calories consumed, caffeine levels, hydration, and more. Users can set goals within the app, tracking all of these metrics and more. Vessyl also tracks and estimates a person's real-time hydration needs based on how much they drink, which is measured through the liquid level in the cup.
Vessyl, which holds 13 ounces of liquid, has a built-in display, a spill-proof lid, and a non-stick interior. It connects to an iPhone using Bluetooth 4.0 to upload nutrient data to its accompanying iPhone app, which also integrates with popular activity trackers. The cup lasts for five to seven days on a single charge and uses wireless charging.
Vessyl can be pre-ordered for $99, but will later retail for $199. It is available in three different colors (Shadow, Snow, and Steam) along with several accent lid colors, and it is expected to begin shipping in early 2015.
