Not a scanner app! Why didn’t I read the reviews?
I did read a review, but not in the App Store, it was an article on the web. Being new to OBD-2 I just assumed an app for it would connect to my device via Bluetooth. This app is just a list of error codes! It’s useful if you have an old OBD device that only scans codes, then you can read from the device and look up the error codes returned. Only reason I gave it 2 stars instead of 2.
