HA Cloud and the IOS App Capabilities

I’m having a bit of trouble nailing down exactly what the HA Cloud server does now, perhaps someone can clear it up for me? Here’s what I think I know or don’t; please correct me if I am wrong:

  1. It will provide remote access to a HASSIO instance (as of 0.90) via the HA iOS App.

  2. It provides push notifications via the HA iOS APP.

  3. Via the new remote access capability, does it provide GPS presence detection/updates when I am NOT home - to my HASSIO instance at home - natively via the iOS App?
