Poor UX, crashes constantly
The good news: it’s free (from the App Store) I was really hoping that the ‘lite’ version of the app would offer reliable simplicity - but it has neither. Each app instance needs to be configured on the controller by the dealer, the UX is extremely non-Apple and not very intuitive, and the app crashes constantly and randomly (I.e. there is no single procedure that reliably triggers a crash - but the app always crashes eventually).
