Nutri Expert Limited is a Hong Kong–based technology company specialising in the development and monetisation of high-impact mobile health applications. Our apps, FoodAmigo and Calorie Papa, turn a photo or a sentence about a meal into an estimate of its calories and macros.
Incorporated in Hong Kong, Nutri Expert Limited focuses on the full lifecycle of health-focused mobile applications—from concept and development through to commercial monetisation. We combine deep nutritional science with intuitive design and AI-driven personalisation.
Native iOS apps built to the highest UX standards with focus on retention and engagement.
Subscription and in-app purchase models designed for long-term revenue growth.
AI that recognises a meal from a photo, a sentence or a voice note and estimates its calories and macros.
Products distributed on the App Store, with FoodAmigo available in English, Spanish, Portuguese, French and Turkish.
A Hong Kong Company dedicated to developing the next generation of digital health applications. Our products bridge evidence-based nutrition science and consumer-grade mobile experience.
Each application is engineered for high user retention, viral growth loops, and diversified revenue streams.
Log a meal the way you'd tell a friend. Snap it, pick a photo from your library, or just type what you ate — FoodAmigo works out the calories and macros, tracks intermittent fasting, and shows your day, week and month in one place.
Requires iPhone with iOS 17 or later. Sold as a subscription.
Snap your meal. Papa does the math. Log a meal by photo, voice, or a few words — Papa comes back with calories, protein, fat and net carbs in seconds. No barcodes. No endless searching.
Free to start. Calorie Papa Pro is an optional auto-renewing subscription.
We follow a rigorous, data-informed development process that ensures each application is scientifically sound, commercially viable, and genuinely useful to end users.
We identify under-served niches within the health and wellness space, validate user demand through qualitative research, and model monetisation potential before committing to build.
Features and recommendations are grounded in peer-reviewed nutritional science. UI and UX decisions are driven by behavioural psychology to maximise healthy habit formation.
We build food recognition on top of leading AI models and design the experience around them — portions you can correct before saving and every number shown as an estimate.
Post-launch we iterate on conversion funnels, ASO, and monetisation including subscriptions, trials and partnerships to maximise LTV.
We do not sell personal data. Meal photos and descriptions are used only to estimate nutrition and are not kept once the result is delivered.
Targets and calculators use published formulas such as Mifflin–St Jeor, and every AI result is shown as an estimate — never as a medical measurement.
We build for longevity, favouring organic acquisition and genuine user value over paid growth that doesn't last.
We release regular updates driven by user feedback and App Store performance analytics.
Whether you are a potential partner, investor, or developer, we welcome conversations about the future of mobile health.
