Meet Spün: a smart utensil that lets you count calories and track macronutrients easily. It has a weight sensor and gesture recognition to detect the weight of food in your every bite. Its mobile app provides you with calories and macronutrient information. As Spun gets to know you, it recommends healthy meals.
Spün comes with a water resistant handle, interchangeable head attachments, and disposable heads. To use it, just take a picture of your food, circle your portions, verify selections, and power on the device. The battery lasts all day. You can find out more about it on Kickstarter.
