OBD Car Doctor Review. Instant Car Diagnostics

If the ‘check engine’ light or MIL keep giving you trouble and you don’t know how to read them, let OBD Car Doctor be your guide.


The black contrasted color background is a compelling addition to the interface, though I didn’t find the UI quite intuitive. The speedometer looks very realistic and colorful, but some of the text is quite small. I’ll give it a 7/10.

Key Features

You don’t have to be a car enthusiast to see the usefulness of this app. If you have a smart vehicle, OBD Car Doctor works with your car’s ECU to assess the health situation of your machine among other important parameters.

To use the app, you’ll need an OBD ELM327 adapter, which is attached to your car’s OBD2 port. This adapter acts as the link between your car’s ECU and the app, and you use Bluetooth as the bridge between the adapter and phone. Your car has to be OBD-II or EOBD compliant.

This app assesses your vehicle as a diagnostics scanner, giving you such capabilities as:

  • Advanced diagnostics tools.

  • Emissions monitoring check.

  • Clear Diagnostics Trouble Codes (DTCs), Check Engine, MILs and Freeze Frame.

  • Monitor your fuel consumption daily or over distances and make savings.

  • Relaying OBD-II sensor data either in numerical or graphical formats.

  • View sensor data and parameters in real time and detect abnormalities as they occur.

  • Access and view sensor data for multiple ECUs such as transmission and engine.

You can send the diagnostics and sensor data to your email in .csv format. OBD Card Doctor also has different metric units.

The Pro version of the app will provide users with GPS support, a screen for fuel economy statistics, and reading/displaying various parameters simultaneously.

The latest version offers a bug fix for DTC crashes and also enables support for Lonauto adapters. The features are comprehensive although specific to OBD2-compliant cars. I’ll give them a 10/10.

The app from Google Play and the App Store is free to install, but you can make a purchase of $3.99 for the Pro version.

The app compatibility varies with the Android device, while the iOS version requires at least iOS 9.0 for iPhone, iPod touch, and iPad.


For me, the biggest problem working with the app was the unintuitive UI which I still haven’t got used to. Occasionally my Bluetooth failed to connect, although switching it on and off solved this problem. All the other features I tested worked flawlessly. I give the app a 9/10 for its convenience.

Bottom Line

With all the features that this app offers, it’s not difficult to see why it is the leading OBD app on the market. If your vehicle is OBD-II compliant, you should definitely get this app.
