inCarDoc - OBD2 ELM327 Scanner

OBD2 car scanner and diagnostic tool — inCarDoc - OBD2 ELM327 Scanner turns your smartphone into a professional vehicle diagnostic device. Connect via Bluetooth or WiFi to your car's onboard computer and unlock real-time insights into engine health, fuel efficiency, and performance metrics that help you stay ahead of costly repairs.

Read and clear diagnostic trouble codes instantly. When your Check Engine light comes on, inCarDoc retrieves fault codes, displays freeze frame data, and provides detailed descriptions so you understand exactly what's happening under the hood. Store and share diagnostic reports with mechanics or technicians when seeking professional repair assistance. The app supports all OBD-II compliant vehicles and works with ELM327 adapters plus compatible devices including Bluetooth, WiFi, Kiwi 3, V-Gate iCar 3, Veepeak, Carista, and Vinli.

Monitor real-time engine parameters from your car's sensors. Watch live data including engine speed (RPM), coolant temperature, oxygen sensor readings, fuel pressure, vehicle speed, and dozens of additional PIDs supported by your specific vehicle. Visualize trends with built-in charts and choose from analog or digital gauge displays to track performance metrics that matter to you.

Optimize fuel consumption with the Trip Computer and economy tracking features. Monitor instant and average fuel economy during drives, then review detailed statistics by trip, day, or custom periods. Accurate calculations require your engine displacement and volumetric efficiency settings, helping you identify driving patterns that waste fuel and adjust your habits for better mileage.

Build a complete vehicle logbook within the app. Record fueling events, scheduled maintenance, service visits, and diagnostic sessions all in one organized timeline. Upload your logbook to the web for cloud backup and access from any device. Advanced users can access console mode to send custom OBD2 and ELM327 commands, while GPS mode provides speed and altitude data even without an active scanner connection.

Register your vehicle profile and contribute diagnostic data to help improve the app's compatibility database. The more users share their car information, the better inCarDoc becomes for everyone. Requires a compatible ELM327 or alternative OBD2 Bluetooth/WiFi adapter — avoid cheap clone versions marked as v2.1, which have known compatibility issues. inCarDoc - OBD2 ELM327 Scanner empowers you to understand your vehicle's health and maintain it smarter.
