## Overview

DigBin is a single-module Android app built with Kotlin and Jetpack Compose, with Firestore as its documented backend. The tree indicates a client-management feature alongside machine, tool, and job-binder domain models. A likely user journey is entering the app and using the client list or add-client screen, but the sampled material does not show the runtime wiring between those screens, view model, repositories, and Firestore. The diagram therefore shows components and the documented external store, while omitting uncertain call relationships.

Main entry points: [`app/src/main/java/com/example/digbin0004/firebase/FirestoreService.kt`](https://github.com/hoosammr/digbin4/blob/main/app/src/main/java/com/example/digbin0004/firebase/FirestoreService.kt) (Firestore service), [`app/src/main/java/com/example/digbin0004/MainActivity.kt`](https://github.com/hoosammr/digbin4/blob/main/app/src/main/java/com/example/digbin0004/MainActivity.kt) (Main activity)
