iPhone remote apps - “Apple TV Remote” vs ... something else?
They are different &quot;apps&quot;.  The one in Control Center is not even a full-fledged app.  You can't switch to it, or close it, like regular apps.  I think I end up using the one from the Control Center more, since it's easy to launch, and I think that's the one that integrates better with Apple Watch (I can use my watch to control the ATV, if I start the remote on my phone first).
Notice the multiple uses of the word &quot;think&quot;.  This is not an obvious design choice by Apple.  The Control Center icon should just call a single full app, just like if you click on the Camera, Alarm, etc, in the Control Center.
