Vessyl
There are all sorts of gadgets out there to help us track our activity — but what about what we're drinking? Meet Vessyl. This ingenious piece of drinkware automatically recognizes what beverage you've placed inside it, allowing it to keep track of things like calories, caffeine, sugar, and fat ingested, and your overall hydration level via a system called Pryme. A slick, built-in hidden screen can show you basic info, and for a more complete view of your hydration habits, simply pair it with your iOS or Android device via Bluetooth and let the companion app handle the rest.
