Introduction

The best OBD2 diagnostic tool is only as good as the OBD2 app connected to it. So, for this article, we’ll explore the different apps currently available on Google Play Store and Apple App Store and give you an insight into what these apps are all about. 

Please remember that most of these apps are going to provide you with a basic scan tool. However, there are some out there that only suit a certain car brand and will basically give you a dealer-style full system scan tool. 

Also, we did not rank the list since some apps can only work with a certain brand of vehicle or are exclusive to Apple or Android. What we did is provide the general features of the app, compatible car brands, prices (converted to AUD at exchange rate during publishing), and a brief description of the app. We added the link to the app’s website for your further research. 

Without further ado, here are some of the best OBD2 Apps in the market today: 

(Note that all these apps work with this OBD2 Bluetooth Scan Tool here)

We can’t keep stressing these enough, though:

  1. Keep your service and repair costs at a minimum when you can do your car’s servicing at your own garage! 
  2. Invest on reliable ELM327 or OBD2 compatible Bluetooth or Wi-Fi adapters.
  3. Purchase your supplemental equipment from a reputable car accessories store
