Kallo is an AI calorie and macro tracker for people who find logging tedious. Type what you ate the way you would tell a friend, for example “two eggs, toast with butter, half a flat white”, or take a photo. Kallo splits the meal into ingredients, estimates the grams and returns calories, protein, carbs and fat from food composition databases, with honest ranges instead of false precision. It understands details like “no rice” or “half the box”, sets daily targets from your body and goal, and works in English and Vietnamese. Built with Next.js, Supabase, Flutter for iOS, and Claude and Gemini models. Free calculators for TDEE, calorie deficit, macros, protein and BMI live at kallo.fit/en/tools.
