SMART HUD is a free Android application developed by RoadPia Inc. It is designed to provide LED Head Up Display navigation for safe driving. The app supports DB updates and device settings to guide drivers with beep sounds and LED signals about speeding and signal violations, fixed and mobile speed cameras, and average speed limits in the area. It also displays the remaining distance to camera locations, the current speed of the vehicle, the current time, and the brightness adjustment using the light sensor.

The app provides LED-based navigation for children's protection zones and speeding and signal violation cameras, and it alerts drivers with beep sounds and flashing icons when they exceed the speed limit. The app also allows users to wirelessly update the safety driving DB using the smartphone app and configure device settings such as LED brightness adjustment, volume adjustment, camera guidance mode, and guidance mode for different vehicle types.
