04Product
CalLog lets people log calories and macros (protein, fat, carbs) by taking a photo of their meal. Its database covers more than 30,000 foods, with a focus on Japanese home cooking, convenience stores and restaurant chains. Its encouraging character, Karo-chan, and a friends feature help people keep logging even on days they overeat.
