Offline-first nutrition decision-support app for CHPS frontline health workers in Northern Ghana — UNICEF AI for Nurturing Care Hackathon # NurtureLink An offline-first nutrition tool that helps CHPS Community Health Officers in rural Northern Ghana turn the visit data they already collect into affordable, in-season feeding guidance a caregiver can actually act on, delivered in local language. It supports the health worker's judgement rather than replacing it. Built for the **UNICEF AI for Nurturing Care Hackathon** (KOICA / MEST StartUp Lab). Bootcamp: 26–28 August 2026, Tamale. > **Status — working offline-first MVP.** The recommendation engine, encrypted on-device storage (SQLCipher), outbox sync, the severe-case referral guardrail, and 50+ passing engine tests are implemented and runnable against a seeded pilot district. Voice audio playback, the longitudinal trend chart, and the DHIMS2 export are in progress for the 26–28 August bootcamp. **Team:** Yakubu Lute (Technical Lead) · Leticia Offeibea (Health & Nutrition Domain) **Jump to:** Screenshots · Recommendation Engine · AI Architecture · Challenge Mapping **Implemented:** client registration · visit capture · dietary-diversity scoring · deterministic recommendation engine · seasonal + affordability food selection · referral guardrail · offline SQLite with outbox sync · at-rest encryption · JWT/PIN auth · reference-bundle versioning · Express + Prisma backend · pilot-district seed data **In progress (bootcamp):** Dagbani audio playback · trend chart on client screen · pull-sync UI · DHIMS2 export serializer · field validation of food/threshold data --- ## Screenshots | | | | | --- | --- | --- | | | | | | **Sign in / offline mode** | **Prioritised caseload** | **Longitudinal nutrition trend** | | | | | | **Seasonal feeding plan** | **Voice note delivery** | **Severe-case referral guardrail** | | | | | | **Referral tracker** | **Visit history** | **Client registration** | | | | | | **Data sync** | **Offline mode** | **Profile & device info** | > Screenshots captured in development on iOS; production target is Andr …
