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.

Ratings and reviews

I can't figure out for the life of me where my logs are saved. As soon as I stop the car everything disappears and the excel logs that I share via email are all blank. Other than that everything seems to work but it's useless without being able to analyze and save data. Edit: ok I figured out the semantics don't leave the screen or the data disappears. Makes sense considering the large timestamp data generated. It would fill up the phone memory very fast.

This is pretty cool. Noticed a difference as soon as I plugged it in and went driving. The only downfall I've ran into is connectivity to my phone sometimes is a pain. It always eventually connects after the 3rd or 4th time trying. That's a big that should be fixed but other then that, I'm super impressed. Planning on getting another one for my other car.

What, I'm the only one this doesn't work with. I have to create an account, give them location permission and the d app doesn't even connect. Ok, follow their troubleshooting guide, try connection over and send log but the log doesn't contain anything, nada. This elm327 adapter works ok with torque but not this app. I was looking for something a bit easier to follow than torque and less buggy but I guess I'll have to stick with that. I've wasted way too much time on this.

What's new

Further stability and performance improvements to make diagnosing your cars as easy as possible.
