Ratings and reviews

Absolutely wonderful and the price is just to good to pass up. Im a hands on type of guy but not very clued up when it comes to cars and this totally bridges that gap, someone could even use this to help them through the process of getting qualified its that good. Try it out seriously and youll be pleasantly surprised how good this actually is. Thanks OBDassistant now my car worries are that much simpler.

Awesome best one yet. Im not a mechanic but the AI tells me the issue, how to fix it and what parts etc. 👍 It's a really great app I highly recommend it.
