Extension Box

Extension Box is a modular Android system monitoring application built around independently controlled extensions.

The app runs a foreground monitoring service and displays live system data through a persistent notification and in-app dashboard cards. Each module can be enabled or disabled individually.

Disabled modules do not execute background logic.
