Good device and app

Works pretty good. Displays all live data really well and is fairly accurate. The only thing I noticed is it does take a few seconds to connect but probably mostly due to Bluetooth technology. Looking at other reviews, please do your research on compatibility. This app works best with the iobd2 Bluetooth device that you can get fairly cheap on ebay. Elm327 is also very limited on functionality

A nickname of some sort about iOBD2, v5.3
