LOTS of potential.

This app will be great if it evolves. Lots of bugs to work out. CarPlay interface is a little boring and small despite plenty of screen. Some CarPlay readings only display in Celsius although Empirical selected in settings. Only used a few times but I’m excited for it to improve. Successfully connecting with vLinker MC

Response from developer

Thanks for the feedback. Due to CarPlay’s current design limitations, I’m not yet able to offer the fully custom and creative interface I have in mind, but I’m actively working on improving it and making better use of the available space. I’ll also look into the bugs you mentioned, including the Imperial/Celsius issue, as soon as possible. Thanks again for helping improve OpenOBD.
