OBD2 Scanner: Car Doctor
AppUpdo
Turn your Android phone into a practical OBD2 scanner and vehicle health assistant. Connect a compatible Bluetooth ELM327 adapter to read and clear diagnostic trouble codes (DTC), monitor live engine data, and organize vehicle maintenance in one place.
OBD2 DIAGNOSTICS
• Read stored diagnostic trouble codes from your vehicle
• Clear fault codes after repairs when supported by the vehicle
• Understand common DTC codes with built-in descriptions
• Search fault codes even when you are not connected
• Keep a diagnostic history for your vehicles
LIVE VEHICLE DATA
Follow supported sensor values in real time with a clear, modern dashboard:
• Engine RPM and vehicle speed
• Coolant and intake air temperature
• Battery and control module voltage
• Engine load and throttle position
• MAF, manifold pressure and fuel-related data
• Timing advance, engine runtime and additional supported sensors
VEHICLE INFORMATION
• Read available VIN and ECU information
• View emissions readiness monitor status
• Check supported OBD2 protocols and vehicle data
• Generate and share a PDF vehicle health report
SMART GARAGE & MAINTENANCE
Manage more than diagnostics. Add your vehicles to the garage and keep important ownership records together:
• Create service records and plan the next maintenance by date or mileage
• Track fuel purchases, consumption and fuel costs
• Record vehicle expenses by category
• Follow inspection, traffic insurance and comprehensive insurance dates
• Track tire installation and replacement mileage
• Create reminders for service, documents and custom tasks
DESIGNED FOR EVERYDAY DRIVERS
OBD2 Smart Scanner combines a fault code reader, live data monitor, car maintenance tracker, fuel log and vehicle garage in one easy-to-use app. It helps you notice problems earlier, prepare before visiting a workshop and maintain a clearer vehicle history.
MULTILINGUAL
Use the app in English, Turkish, German, Polish, French, Italian, Spanish, Arabic, Simplified Chinese, Brazilian Portuguese, Mexican Spanish, Hindi, Japanese or Korean.
COMPATIBILITY
A compatible Bluetooth ELM327 OBD-II adapter is required for connected diagnostic functions. Available sensors, fault-code operations and ECU information depend on your vehicle, ECU and adapter. Compatibility can vary between vehicle models and adapter versions.
IMPORTANT
Use live data only when it is safe to do so. This app provides vehicle information and maintenance organization tools; it does not replace inspection or repair by a qualified automotive professional.
