## Overview

Posyandu Digital is an Android client and Express backend for digitizing child growth monitoring. Parents and cadres register or sign in, manage child records, and record measurements; cadres also verify parents, while role-specific dashboards and reports expose monitoring results. The app uses Retrofit to communicate with the server, and the README describes offline-first measurement capture and background synchronization. The sampled sources show backend routing, authentication, child management, and dashboard calculations; several other capabilities are documented or indexed but their implementation details were not inspected.
