 #### Use your Phone
-- iPhone: Our Penguins tend to prefer the [Head Tracker app by John Yu](https://apps.apple.com/us/app/head-tracker/id1527710071). It works on iPhone X or later using the FaceID IR sensors and, therefore, works well in low light. It has a trial period to test it out. It costs $2 US
-- Android: Our Penguins tend to like the [SmoothTrack app by John Goering](https://play.google.com/store/apps/details?id=com.epaga.smoothtrack&gl=US). It costs $10 US

 #### Webcam
+- You can build [Opentrack with the ONNX Runtime](#building-opentrack-with-onnx-runtime) to add a neuralnet tracker that enables head tracking with any webcam.
 - A tutorial for the the ArUco Paper Method is written in our Org's [Spectrum Forums](https://robertsspaceindustries.com/spectrum/community/LUG/forum/194647/thread/tutorial-opentrack-aruco-for-star-citizen-via-lutr). (Note: Ignore the outdated Opentrack installation steps in that thread)

 #### Unsupported hardware
 - Tobii does not support Linux. Its opentrack support uses the Windows only SDK.
+- TrackIR support is complicated. Linuxtrack may support it but not under wine/proton. We recommend Delanclip instead.
