CRAB Car Scanner is a free Android application designed to provide an intuitive OBD (On-Board Diagnostics) scanning experience. The app features a user-friendly interface that allows users to display key performance parameters of their vehicles directly on their car's screen or Android device. Users can set acceptable ranges for various parameters, receiving automatic notifications for any deviations, which enhances vehicle monitoring during drives.

The app integrates seamlessly with AGAMA Car Launcher for users seeking a more unified interface for in-car applications. This integration allows music, navigation, and radar detection to be displayed alongside OBD data, creating an aesthetically pleasing and comprehensive management system. With a lightweight installation size of only 4 MB, CRAB runs efficiently in the background, connecting to OBD without requiring additional input from users.
