What is an OBD2 Scanner App?

An OBD2 scanner app refers to a mobile or desktop program that interacts with your car's onboard diagnostics (OBD-II) system with the help of a supporting adapter (like Bluetooth or Wi-Fi ELM327, or USB ELM327 device). These apps enable vehicle owners and mechanics to read and clear Diagnostic Trouble Codes (DTC), monitor the "Check Engine" light, and weigh out sensor data in real time- engine RPM, fuel economy, coolant temperature, and so on. Many OBD2 apps also provide advanced features such as emission readiness, performance monitoring, trip logging, and modification of some car functions, making for a very handy and economical means for maintaining and troubleshooting cars.

Imbued with proper integration of mobile app development, these tools now offer instant diagnostic details about the vehicle to the driver on any smartphone. You may think of it as the car “talking” to you - enabling you to detect any issues early and unexpected breakdowns on the road-free.

The majority of these OBD2 apps provide access to important engine and vehicle data in an instant and in real time. These parameters may include speed, rotation angle, pressure, temperature, fuel efficiency, or emissions readiness.
