Wanted to share that I bought the SmoothTrack App for head tracking abilities for the sim. It works great! Setup was simple, especially now there is an update to use USB connection for reduced latency (and keeps the phone charged). After a few minutes I got used to moving my head to look around and zoom in. I love how simple the setup is, nothing to wear on my head. You can turn off the screen so there is nothing distracting to look at. For $9.99 it’s perfect! Recommend you try it out.
