NanoRhino is an AI nutrition coach that lives in your text messages - no app to install. It starts with the most accurate free TDEE calculator we could build: instead of asking you to pick one of five activity levels (which hides a 300-500 kcal/day error), an AI interviews your actual day - job, steps, commute, cooking, workouts - and computes a calibrated calorie range with BMR, NEAT, TEF, and exercise broken out, every number traceable to a published formula.
From there, the coach texts with you over SMS or WhatsApp: snap meal photos for macro estimates, get a personalized plan, and build habits with gentle check-ins. Pricing is results-based - $10 per pound lost, capped at $500. No subscription, no upfront fees. Adults only (18+), US-first.
