## What is Metabolic Computer by Sam Gym?

Metabolic Computer by SAM GYM is your personal fitness supercomputer. Snap a picture of your food to track calories and macros. Then it combines your workouts, nutrition, and health data into one system that shows your current calorie intake from food, and your calorie expenditure from your wearable heart rate monitor, like a WHOOP or Apple Watch.
The app pulls real data from Apple Health or WHOOP — recovery, strain, heart rate, sleep — and combines it with your logged workouts and meals to build a personalized metabolic picture. From there, it forecasts your weight and gives you daily calorie and macro targets calibrated to your goals.

FEATURES:
• AI-powered weight forecast based on your actual activity and food intake
• Smart calorie & macro targets that adapt to your real-world data
• Meal tracking with photo analysis — snap a plate, get the macros
• WHOOP and Apple Health integration for recovery, strain, sleep & heart rate
• Workout logging with muscle recovery insights and AI recommendations
• Heart rate zone analysis with weekly training targets
• Detailed history with fully editable workout and meal logs
