AI calorie tracker live on iOS and Android, with its own food data pipeline
NutriscanIA turns a photo of a meal into a full nutrition breakdown. The user photographs their food, the AI identifies the dish and its ingredients, they confirm the result, and the app logs calories and macros against a personalised target calculated at onboarding from BMI, BMR and TDEE. It is live on both the App Store and Google Play. It has no users and no revenue. I never marketed it, and that is exactly why I am selling. WHAT MAKES IT MORE THAN A GPT WRAPPER Most apps in this category are a thin layer over an AI API. This one has a real data layer underneath: Ingestion pipelines for USDA FoodData Central (public domain) and Open Food Facts (ODbL) A concept, alias and measure model that resolves "1 cup of rice" into grams Barcode lookup that logs every failed lookup as a coverage gap to backfill A recipe engine with ingredient resolution A manual nutrition-correction layer over imported data 13 versioned Flyway migrations WHAT IS INCLUDED Both live store listings, ready to transfer Around 18,400 lines of production code across 296 files, in two repositories React Native app: Expo 54, TypeScript, expo-router, NativeWind, Zustand, New Architecture Spring Boot 3.3.5 backend on Java 21, PostgreSQL with 18 tables, JWT auth, Swagger, Docker deploy script The nutriscania.com domain Full setup documentation and 30 days of handover support ALREADY BUILT Onboarding with the nutrition maths, photo scanning and manual food entry, daily log and dashboard, weight tracking with goal projection, Google, Apple and Facebook sign-in, subscriptions with vouchers and cancellation, push notifications, three scheduled re-engagement jobs, in-app account deletion, analytics and crash reporting. Spanish and English, metric and imperial units. WHY I AM SELLING I built it on my own and took it all the way through review on both stores, but I never had the time to market it. The product is finished and running. What it has never had is anyone promoting it. For a buyer who can handle distribution, the engineering is already done. HONEST NOTES No automated test suite. The scan cache is single-instance, so horizontal scaling needs work. Payments are wired to MercadoPago and will need swapping for most markets. Android subscriptions currently run outside Play Billing. Open Food Facts data is ODbL licensed, so the pipeline and importers transfer but the buyer populates their own database. WHAT YOU WILL NEED Apple and Google developer accounts, plus your own OpenAI, Firebase and AdMob accounts.
Next step: <p>There is a clear runway of work that is already scoped or half-finished:</p><p><br></p><p>- Wire up barcode scanning. The lookup API is built and working, including coverage-gap logging, but no screen uses it yet. This is UI work on finished infrastructure.</p><p>- Finish the portion selector and the improved food search. Both exist on an unmerged branch.</p><p>- Swap payments to native billing. Google Play Billing and StoreKit, replacing the current MercadoPago flow, which also removes a policy risk on Android.</p><p>- Move to a current vision model. The OpenAI model is pinned to an older snapshot; newer ones are cheaper per image, which improves margin immediately.</p><p>- Do the ASO that was never done. The listings have no keyword work at all.</p><p>- Launch in English. The app already ships English copy and imperial units, so the largest market is one store listing away.</p><p><br></p><p>The engineering to a shippable product is done. What has never been attempted is distribution.</p>

The two published store listings transfer with the sale: the App Store app and the Google Play app, including their review history and the bundle identifier. This is the largest single item in the sale and there is no checkbox for it above. Also included: the PostgreSQL database with 13,468 food items (8,005 from USDA FoodData Central, 5,101 from Open Food Facts, 565 recipe components), the ingestion pipelines that produced it, 13 versioned Flyway migrations, full setup documentation, and 30 days of handover support by email. Not included, because the buyer needs their own: OpenAI, Firebase, AdMob and MercadoPago accounts. The setup guide covers configuring each one.
