Both the user interface and user experience are nice for this app and it's easy to navigate, but it certainly makes a lot of mistakes. I use Bluetooth on my phone and Spotify to listen to music while I drive. I also use Google maps for navigation all the time. Even if I just place my phone on the phone holder on my dash and don't touch it, it seems as though if I'm using those apps it still registers as "phone use". That's pretty frustrating since I'm not actually using my phone.
