Ratings and reviews

Great app , makes OBD2 codes easy yo understand and explains next best steps rather than just confusing data. the AI diagnostics , live data, brake and dyno tests make it feel like a true car health tool , highly recommended.

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.

this is 100 percent the best diagnostic app there is the break and suspension tests work rely well the ai chat is spot on with its responses I won't be using anything else now keep up the good work obdassistant cant wate to se what future updates will bring 👍
