OBD Terminal is a universal iPhone/iPad app that allows you to communicate with any OBD compatible vehicle, via an ELM327 Bluetooth 4(LE) or WiFi adapter.

NOTE: This is a low level communication app for individuals with specific technical knowledge. Not for simple fault code reading.

Current ELM commands are available in an easy to use format, that gives a full description of their purpose, as well as step by step parameter help.

Standard OBD commands are also available, with associated parameters.

All commands are searchable by name or description, to help you to find the right command for the job.

Fully customisable connection settings for compatibility with all WiFi OBD adapters and most Bluetooth 4(LE) adapters.

Share function to forward diagnostic results to notes, email, messages, clipboard, etc.

Custom keyboard to aid in hex code input, but also switchable to standard iOS keyboard, or any other custom keyboards you have installed.

More features coming soon.

Ratings and Reviews

Great tool.


I bought this as a tool for learning more advanced techniques for troubleshooting. There was a bug with the interface that was caused by an iOS update. Went to the developers website got his email and reported the bug. he or she responded to me the same day and was able to let me know that the update would be coming soon. I reported last Friday today is the following Monday, the update fixed the problem that I had encountered. Fantastic customer support/response. Only feature request that I request is an About tab with contact info and website link.
