OBD Info-san is a handy tool for car owners to know more about their vehicle. By connecting to an ELM327 Bluetooth device, this application is able to show information such as fuel consumption, tire pressure, brake discs, and the vehicle's engine and transmission information. In addition, it is possible to check the car's drive quality by checking the average fuel consumption, mileage, and the stopping time.

The app can also show the vehicle's location, current speed, altitude, and the current time. In addition, it is possible to check the status of the OBD connection, and the trouble code and warning code.
