This app seems awesome. Using with my r8w! Super happy to see an app that uses CarPlay. Having issues right now with it crashing every time I put in navigation. Crashes on CarPlay and on my phone. Also the phone shows miles while the CarPlay shows meters/kilometers. Ive got an up to date 16 pro max in a 2021 Nissan Altima.
Great app

Have it connected to the v1, works really, consistent updates and tweaking. Super fun to use and compare to the competing apps. All have their quirks but im leaning towards this one as the daily.

Great app and love all the customization but it’s just another screen for a Radar Detector without the crowd sourced police alerts
