Meet the YuScale GO: a smartphone case with a built-in scale that lets you track your eating habits. It has up to 4kg capacity and lets you measure nutritional values of your meals. Simply weigh your dish, take a photo, draw outlines, and rely on the app to track the results and maintain a food diary.
YuScale GO is expected to be compatible with iOS and Android devices. You will be able to use the app to add notes, mood, and other info. More info is available here.
