OBD2 scanner apps work in conjunction with an OBD2 adapter that plugs into your car’s OBD2 port, typically located under the dashboard. The adapter communicates with the app via Bluetooth or Wi-Fi, transmitting data from your car’s computer to your Android device. The app then translates this data into user-friendly information, allowing you to:

• Read and Clear Trouble Codes: View diagnostic trouble codes (DTCs) and clear them after addressing the underlying issue.
• View Real-Time Data: Monitor various engine parameters such as engine speed (RPM), coolant temperature, and oxygen sensor readings.
• Create Custom Dashboards: Display the data that is most important to you in a customizable dashboard format.
• Record and Analyze Data: Record data logs for later analysis and troubleshooting.

1.3. Key Features to Look for in an OBD2 Scanner App

When choosing an OBD2 scanner app for your Android device, consider the following key features:

• Compatibility: Ensure the app is compatible with your car’s make and model. Some apps offer enhanced diagnostics for specific brands like Mercedes-Benz.
• Ease of Use: Look for an app with a user-friendly interface and intuitive navigation.
