Killer App in this instance really means “a use case that justifies the cost”

To it may concern:

No I didn’t actually.

I’ve never bothered with the app.

I just use airplay and let HomeKit handle it and have had absolutely 0 issues with it.

My appleTV discovered it and provided it to HomeKit and I was done.

I’ve had my Sonos sound bar controlled by HomeKit since the day I bought it and have never needed to fuck with their app.

I guess I got lucky?

No, I am Benchy!
