## Overview

Chatiko is an Android app whose named features cover account access, chat, nearby-vibe discovery, preferences, settings, and a tutorial/home screen. The tree suggests the user-facing flow starts at the app activity and branches into these features, with ViewModels and network helpers providing internal layers. The README is empty and only build configuration was sampled, so screen navigation, API calls, persistence, and feature-to-service wiring cannot be verified; uncertain connections are omitted.

Main entry points: [`app/src/main/java/com/example/chatiko/ui/spalsh/MainActivity.kt`](https://github.com/angelvtony/chatiko/blob/main/app/src/main/java/com/example/chatiko/ui/spalsh/MainActivity.kt) (Main activity)
