Wow. The App has a huge lead coming out of the gate.
For me, I just don’t have a need for the app. I’ve already set up my dashboards the way I like, and they look great on both mobile and desktop browsers. I already have at least three browsers on my phone.
Then again, I don’t do presence detection, which I imagine is improved with the app. In which case I totally get why someone would go that route.
I think far too many apps are little more than screen scrapers for the manufacturer’s web site, with the only advantage being their ability to collect more data about the user. Obviously this doesn’t apply to HA. Just my observation that maybe we collectively jump to installing an app for everything a bit too quickly, when a browser will work just as well and give us more control and privacy.
I use the phone app mainly for notifications, and because it is the recommended method for adding Matter devices due to Bluetooth requirements.
For security reasons, I do not allow incoming (remote) connections to my HA so the app is useless to me for location detection or actionable notifications, both of which require ad-hoc server access.
I do have an android tablet in my kitchen running the app with a custom dashboard, but generally find it tedious to construct dashboards.
To interact with my home, I export relevant entities to Apple Home and prefer the Home App / Siri.
To get any configuration work done I use HA in safari on my iPad or Mac mini.
