It’s ok. Their app isn’t great, but the underlying technology is. Spotify can directly play to one of their speakers. Their local protocol is also well understood and you can do most things with it, so you can vibe code your own replacement app pretty easily. The problem is once you hit their cloud APIs the latency is way too high for something like a speaker.

Yeah, the hardware is great. I honestly couldn't tell you much about the app because I exclusively use the speaker via HDMI-ARC and AirPlay, both of which work really well.
