Previous Comments are still true...
I'm using Haas.io companion for iOs for a while now, and what I can confirm is that is a crazy, smooth, and user friendly companion to Hass.io.
Everything works well, even custom components.
Notifications, for example, work perfectly and it's flawless...
A big HUG to the developer who made a crazy good job here, and even not directly affiliated to Home Assistant...
Thank you then, a lot :)
