What is an OBD2 App and How Does it Work?

OBD2 stands for On-Board Diagnostics, generation two.

An OBD2 app acts as the interface between your phone and your car, translating complex data into user-friendly information.

To use an OBD2 app, you’ll need an OBD2 adapter, a small device that plugs into your car’s OBD2 port (usually located under the steering wheel). This adapter connects to your phone via Bluetooth or Wi-Fi, allowing the app to communicate with your car.
