TERRIBLE APP - DO NOT USE Takes app 5 to 10 minutes just to connect to OBD adapter. And even then you're bombarded with ads before you get any results. DO NOT RECOMMEND.

Thank you for your rating. It's impossible to connect with an OBD2 adapter in 5-10 minutes because the app has a connection time limit of 30 seconds. The app works perfectly, which is why we have over 2 million users and high ratings!

this app used to allow you to reset codes. There are better free options now.

Perhaps the product is outdated and no longer works but I can't get it to give me the engine management icon so I can track down the code it's throwing. Don't know if it's too old or what? Also now there are so many ads, it's nearly impossible to navigate. I haven't used it for a while and it certainly doesn't work like it used to. 🤷‍♂️😢🤔
