Smart Settings FREE is a utility tool designed for Android devices that allows users to automate system settings based on the application currently in use. This app provides the capability to manage features such as auto-rotation, screen brightness, Wi-Fi, and Bluetooth, enabling or disabling them as specific applications come to the foreground. Users can customize these settings individually for each app, enhancing user experience by optimizing device performance according to the task at hand.

The application supports two profile modes: 'Normal' for enabling settings on selected apps and 'Invert' for disabling settings on those apps. The free version of Smart Settings allows configuration for up to two applications simultaneously. Notably, the app automatically restarts after device reboots, ensuring persistent functionality without requiring manual intervention, while still offering the flexibility to adjust settings through the device’s system settings.
