I’ve tested most of the current Android apps.
With every each of them I have issues either regarding visual side or vision for development.
I’ve just looked up HA App in Apple Store (as I don’t own apple device) - and it’s exactly what I would require from app! It supports GPS, notifications and pure webview.
I like my lovelace UI, why does all the devs try to do anything with that… 
I hope to see just an clone from iOS on Android and called ‘official’ so it’s always up to date with the API and growing with HA.
