Turn your phone into a capable car diagnostic tool. Connect a standard, compatible Wi-Fi OBD-II adapter and read what your vehicle's computer is really reporting — trouble codes, live sensor data, readiness monitors and more. WHAT YOU CAN DO - Read and clear trouble codes. Scan the engine and other control modules for current, pending and permanent diagnostic trouble codes, then clear them after a repair. - Understand every code. A built-in offline library explains what each code means, its likely causes, common symptoms, suggested fixes and a typical repair cost range. No internet connection needed. - Watch live data. Real-time engine speed, vehicle speed, coolant and intake temperature, engine load, throttle position, fuel trims, airflow, timing and more on smooth custom gauges and charts. - Check battery health. Follow charging voltage with clear resting, cranking and charging readouts. - Readiness and freeze frame. See which emissions monitors are ready before an inspection, and view the sensor snapshot captured when a fault was set. - Service resets and guides. Step-by-step guidance for common maintenance procedures. - Reports. Save any scan and export a clean PDF to share with a workshop or keep for your records. - Garage. Store several vehicles and switch between them in a tap. - Knowledge base. Plain-language articles that explain codes, monitors and how the whole system works. COMPATIBILITY Works with most vehicles that support the OBD-II standard — generally cars and light trucks sold from 1996 onward in North America, and from 2001 (petrol) or 2004 (diesel) onward in Europe. Real-time features require a compatible Wi-Fi OBD-II adapter, sold separately by third parties. Demo Mode needs no hardware at all. PRIVATE BY DESIGN Everything runs on your device. No accounts, no sign-ups, no ads and no tracking. Your vehicle data, code lookups and reports stay on your phone.
