CaloLens: AI Calorie Tracker

Scan meals, estimate calories, track macros and reach your nutrition goals.

CaloLens is an AI-powered meal scanner and calorie tracker designed to make daily nutrition tracking faster and easier.

Take a photo of your meal to estimate foods, portions, calories, protein, carbohydrates and fat. Review the results, adjust the serving size when needed, and save the meal to your daily food diary.

PERSONALIZED DAILY NUTRITION

Enter your age, height, weight, activity level and body goal. CaloLens calculates personalized daily targets for:

• Calories
• Protein
• Carbohydrates
• Fat
• Water intake

Whether your goal is to lose weight, gain weight, build muscle, reduce body fat or maintain your current weight, CaloLens helps you understand how each meal fits into your daily target.

Take or select a meal photo and let AI identify the foods in the image.

Before saving, you can:
