Safemama
A focused barcode-scan plus ingredient-rule engine is feasible for a skilled developer; reproducing a polished, widely populated mobile product with curated coverage and app-store reach is more work and editorial effort than a small DIY build.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Scan barcode → fetch product details → parse ingredient list → match ingredients against pregnancy-caution rules and authority guidance → surface warnings and links in mobile UI
What it still won’t have
- Curated app-store distribution and discoverability
- Any proprietary product database or curated product coverage the vendor maintains
- Ongoing editorial updates and trust signals (brand/marketing)
- Polished cross-platform mobile UX and app-store updates
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a cross-platform mobile app (React Native) with a Node.js + Express backend and Postgres. Core features in scope: (1) barcode scanner screen using react-native-camera to capture UPC/GTIN, (2) product lookup service that queries an external product API (e.g. OpenFoodFacts) or a small seeded product table and normalizes ingredient strings, (3) ingredient parser that tokenizes INCI/ingredient lists and a rule engine that matches tokens against a maintained pregnancy-caution taxonomy (JSON), (4) authority citation page that stores links to FDA/ACOG/NHS guidance and surfaces the source per-rule, (5) caching, offline fallback for last-seen products, user-facing warnings and links, and simple analytics (product scans count). Out of scope: training ML models, medical diagnosis, paid store listing or subscription billing. Include error handling for network, malformed UPCs, and parsing edge-cases; include unit tests for parser and rule engine, and basic end-to-end tests for scan→lookup→display flow.
How we checked
How the score was reached
- Partly verdict base52
- 2 cited sources+1
- Evidence score53
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
