I am super interested in the tech in my Ioniq 5 and already had an ODB BLE dongle and Car Scanner. This purpose-built Ioniq focused app is just what I was really looking for! I had been trying to build my own dashboards in Car Scanner and this is *way* better. I am still exploring all the amazing features available in this app. Thank you for building it just for me! (Or so it feels like)

I’m keeping my eye out for bug fixes. I have really high hopes for this app, but in its current state it’s too unstable.
There is an issue that causes CarPlay to completely stop functioning correctly - and not just for this app - all apps. No navigation, no music, nothing.
It didn’t affect me until the moment I was about to drive off on a roadtrip. When I restarted my phone I even needed to authenticate my apple account again.
I thought the restart fixed everything, but I happened again three more times over the next two days. Finally I deleted this app completely and things are back to normal.
I’ve seen others have this issue too and that the developer is aware and working on it, so again, I have high hopes this app will be great with time.
