OBD2 Car Scanner - ELM Torque is a versatile app designed to assist car owners and mechanics in diagnosing vehicle issues using an OBD2 adapter. By connecting your smartphone to your vehicle's onboard diagnostics system, you can access real-time performance data, read trouble codes, and customize dashboards to monitor specific parameters.

A compatible OBD2 adapter that connects via Bluetooth or Wi-Fi is needed. These adapters plug into the vehicle's OBD2 port, usually located under the dashboard. Choosing a reliable adapter, such as an ELM327-based device, ensures accurate data transmission and optimal performance with the app.

The app does not need a constant internet connection to operate, as it connects directly to the vehicle via the OBD2 adapter for real-time data and diagnostics offline. However, internet access may be necessary for updates, online resources, or troubleshooting guides.

While the basic version of OBD2 Car Scanner - ELM Torque is free, there are optional in-app purchases for additional features.
