Rex.fit

Rex.fit runs an AI service on WhatsApp where people log food intake by snapping photos of meals or typing descriptions. The system identifies foods, calculates calories, proteins, fats and carbs automatically. Users also report workouts through chat for tailored suggestions and receive end-of-day summaries with habit tips. An AI body scanner provides body metric insights beyond BMI. This setup keeps all nutrition and fitness tracking in one conversation thread. Testimonials note ease over apps like MyFitnessPal and better accountability from reports.
