18-Year-Old Founder’s Cal AI Set to Make $30 Million in 2025

Cal AI is a nutrition and fitness app that lets people take pictures of their meals. The app uses artificial intelligence (AI) to estimate the calories and nutrients in the food.

It reports the amounts of protein, carbohydrates, and fats, and assigns a Health Score to show how nutritious the meal is. Users can also log their workouts, and the app estimates calories burned. These numbers are then added to the user’s daily totals.
