This app functions as an OBD2 car diagnostics tool. It allows you to read and clear diagnostic trouble codes (DTC), reset the check engine light, and monitor various vehicle parameters in real-time. It helps you understand your car's health and performance.
Key features include reading and clearing DTCs, resetting the check engine light, monitoring live sensor data (like engine coolant temperature and torque), tracking fuel consumption, and checking readiness monitor status for emissions testing. It also supports initiating service routines and sending diagnostic data via email.
The app is free to download and use, but offers a subscription to unlock all features. The specific pricing and differences between the free and subscription versions can be found on the app's website.
The app supports all cars sold worldwide that are compatible with OBD2 or EOBD standards. You can find detailed compatibility information on the app's website. A separate ELM Wifi OBD2 adapter (ELM327 compatible) or a compatible Bluetooth adapter is required to connect to your car.
Common use cases include diagnosing why the check engine light is on, monitoring fuel efficiency to save money, checking if your car is ready for emissions testing, and understanding real-time engine performance. It's useful for proactive car maintenance and troubleshooting.
