This app is a useful tool for calculating PFC (Protein, Fat, Carbohydrate) balance. A balance of protein, fat, and carbohydrates is important in maintaining a healthy diet. Using this app, you can calculate the percentage of P (protein), F (fat), and C (carb) that you should ingest per day with each calorie element. To ensure a balanced diet, it's important to track your daily intake and adjust it to your health goals.
