Infocar is a vehicle diagnostic app that helps users identify faults in their vehicle's ignition system, exhaust system, electronic circuit, and more. The app categorizes fault codes into three levels to aid the user's understanding and provides detailed descriptions and search functions to find more information about the fault code. Users can also delete fault codes stored in the ECU using the delete function. Infocar also analyzes the user's driving records and provides safe driving and economic driving scores. Users can refer to statistical graphs and driving records to check their driving style and scores for any period they want.

Infocar records mileage, time, average speed, fuel economy, and more for each trip. Users can check the time and location of warnings such as speeding, rapid acceleration, rapid deceleration, and sharp turning on the map. The driving replay function allows users to check driving records such as speed, RPM, and accelerator by time/location. Users can also download their driving logs in spreadsheet format and check their driving records in detail. The app also features a real-time dashboard that displays all the necessary data while driving, including real-time fuel economy and remaining fuel amount. The alert function helps keep driving safe in dangerous situations.

Infocar provides information about consumables and recommended replacement intervals. Users can check the replacement date for consumables calculated using the vehicle's accumulated mileage. The app also allows users to organize their expenses by creating a balance sheet and checking them by item/date. Users can plan their spending with a balance sheet and consumable replacement cycle. The app is compatible with universal OBD2 terminals based on the standard international OBD2 Protocol, but some functions are limited when using a third-party terminal.

To use Infocar, users must have Android 6 (Marshmallow) or higher. The app requires access to location, storage, drawing on top of other apps, microphone, and camera. Users can send an email for system errors and other inquiries such as Bluetooth connection, terminal, vehicle registration, etc., by going to Infocar 'Settings' - '1:1 Inquiry' to receive detailed feedback and app updates.
