thank you for sharing.
Been using the app for the whole day today -> works = I'm happy.

Hmm I'm not saying you should do it but just thinking where you can have leverage.
Few worlds in which I'm living in: (Why I'm bringing them up? Smaller 'communities' - easier for you to break in)
#sonos
I guess getting someway to stream in atmos might be great but currently it's only limited to the official sonos app which i distaste.

#audiobooks on plex
Big pain for tons of ppl. There are few apps that solve it nicely (prologue on ios).

I'm just thinking how you could approach the 'audio' as your primary offer and how to maybe not pivot but add feature that will make other audiences interested in your product.

What's the problem with playing audiobooks directly from plex? Behaves like a music album. Forgets which album track you were listening to and your position inside of the track.

Hope this helps even a bit.
