About the business

NanoRhino is an AI nutrition coach available via SMS and WhatsApp that personalizes weight-loss plans based on your actual calorie burn, measured from your own meal logs and weigh-ins rather than formulas. Users start with a free two-week measurement phase where they log meals and weigh in twice weekly; after week three, the coach recalculates daily targets every week based on real data. When progress plateaus, a human nutritionist reviews your logs and habits to identify the underlying cause and suggest one specific fix.
The service operates without a subscription or upfront card requirement. Pricing is results-based: the first two weeks are free, then you pay $10 per pound actually lost, settled at five-pound milestones, with a $500 lifetime cap. The same pound is never billed twice, and plateaus cost nothing. The system measures calorie burn by the equation: calories logged plus weight lost (approximately 3,500 calories per pound), tracked over at least two weeks of meal logs and weigh-ins.

How does billing work?
Your first two weeks are free with no card required. After your week-two weigh-in, you pay $10 per pound lost, settled at five-pound milestones via a payment link. The same pound is never billed twice; if weight bounces back, re-losing it is free. Plateaus cost nothing. The total is capped at $500 for your lifetime membership.
Is a real person involved or is it all AI?
Day to day, your coach is AI—it answers in seconds, logs meals, and checks in on you. When progress stalls, a human nutritionist reviews your meals, weigh-ins, and habits to find the cause and gives one specific fix. NanoRhino is not medical care and does not diagnose, prescribe, or replace your doctor.
Do I need an app to use NanoRhino?
No app is required. In the US, text START to (915) 277-7888 to begin. Outside the US, message on WhatsApp from nanorhino.com/message. Your coach communicates entirely through SMS or WhatsApp—no separate application to download or login to remember.
Does NanoRhino work with GLP-1 medications like Ozempic or Wegovy?
Yes. About 20% of active users are on a GLP-1. NanoRhino complements the medication by focusing on protein intake (to protect muscle on suppressed appetite), hydration, and calorie adjustments as weight changes through dose modifications. The service does not medicate, prescribe, or give medical advice—your doctor manages dosing.
What is NanoRhino?
NanoRhino is an AI nutrition coach you text. You start with a free Starting Plan — a calorie estimate that's a guide, not a rule. For the first 2 weeks you just log meals (a photo is enough) and weigh in twice a week; from that data we measure what your body really burns, and in week 3 you get your real plan, retuned every week after. When progress stalls, a human nutritionist looks at your data and gives you one specific fix. Your first 2 weeks are free; after that you pay $10 per pound you lose, capped at $500.
