I haven't tried it, but I am interested. The main feature I'm looking for is hands-free use (reading messages aloud, replying, responding to commands). This doesn't mention any of that but I might give it a try.
In the old Android Auto you used to be able to just turn it on and get all those functions but after Google got rid of that and keeps changing how we use phones while driving betwwen apps they keep cancelling, the only thing I know to access it now is to turn on Google maps with navigation to a destination which is pretty freaking annoying when all I'm doing is driving back and forth from work and I don't need all Google Maps commentary about which turn I should or should not be taking or that I'm in the parking lot rather than driving into the front door.
Edit: I installed it. I first tried to find it on F-Droid, it wasn't there which seemed odd. So I installed it from Play Store. It's a FOSS frontend that requires you to sign up for damoov account. Basically it seems to just be a demo app for damoov API. No idea what damoov is and what they're doing with the data. Based on what they mention in Play Store and the startup screens, my guess is they are an API intended to be used by insurance companies to develop apps that monitor policy holders.
