OBD Auto Doctor supports all cars sold worldwide compatible with OBD2 or EOBD. Please see https://www.obdautodoctor.com/help/articles/obd2-compatible-cars/ for the compatibility info.

The app requires a separate OBD adapter using Bluetooth, BLE, or Wifi. Plug the ELM 327 compatible scan tool into the car's diagnostics port, and make sure you are ready for car inspection. We recommend avoiding the cheap clone ELM devices and using genuine ELM327 adapters.

NOTE: Most app features require your car to support them. This app can't show information that your vehicle doesn't provide.

The software works well. I have the yearly subscription and went to use the software and it did quit working. I tried to log out and it wouldn't let me. It said I didn't have a subscription so I ordered the monthly subscription only to find it still didn't work. I finally figured out that uninstalling and reinstalling fixed the issue. I contacted help and they gave me a refund for the 1 month subscription. Happy customer again.

It only scans Engine Control Module (ECM) and Transmission Control Module (TCM). It does not scan any other modules such as ABS, VSC, etc. So it's about the same as a cheap handheld scanner in that regard. The Pro version also has sensor monitors with data graphing and logging, which made it worth it for me to do a one month subscription. This part helped enabled me to figure out the problem with the car. But I had to use something else to read the ABS and VSC codes since OBD Auto Dr. doesn't read those... It paired fine with my Carista adapter, which is just a ELM v1.5 with v4 Bluetooth that works with Android, IOS, Windows.

I love this app! I would definitely recommend upgrading to the pro version for all the features. I use it with the icar pro OBD2 adapter, I've used both the Wi-Fi and the Bluetooth adapter types and have had better luck with the Wi-Fi version as far as connectivity between the device and the application. This app is easy to use and navigate and has saved me so much time in troubleshooting car issues. I tried many others before and AutoDoctor is the best. Thanks guys, keep up the good work!
