Calvion is an AI calorie scanner and nutrition tracker for iPhone and Android. You photograph a meal and the app identifies the foods, estimates portions and logs calories and macros (protein, carbs, fat), alongside water, activity and progress analytics.

Take a photo of your plate. Calvion's vision AI recognizes each food, estimates the portion size and calculates calories and macronutrients within seconds. You can review and adjust every result before it is saved to your food log. Estimates are for general wellness, not medical advice.
