About this tool

Traditional TDEE calculators collapse your life into one of five activity levels, hiding a 300-500 kcal/day error. NanoRhino's free AI calculator interviews your actual day in 5-7 questions - occupation, steps, commute, housework, workouts - and returns a calibrated TDEE range with BMR, NEAT, TEF, and exercise broken out, every number traceable to a published formula. Then the AI coach texts with you over SMS/WhatsApp: snap meal photos for macro estimates, get a personalized plan, build habits with gentle check-ins. No app to install. Results-based pricing: $10 per pound lost, capped at $500.
