## Overview

Downtime Supervisor is an Android operations app for production-line downtime and maintenance, serving dispatchers, mechanics, warehouse staff, and administrators. The main user flow starts in the Compose app and exposes dashboard, equipment, work-order, inventory, analytics, and profile functions; the profile includes theme switching. Separate legacy activities cover login and role-specific scenarios. The data layer is documented as using Room locally and Retrofit for backend exchange. The README establishes these capabilities, but no application source excerpts were provided, so internal calls and screen-to-data wiring are not asserted.
