Customer Reviews
"Installation took a couple of minutes on the PC and after the latest update is now smooth as butter. Looking forward to more improvements! Works perfectly on Euro Truck and other racing sims I play like Assetto Corsa etc"

"I sold my TrackIR headset some years ago and missed it now in the new Flight Simulator - and guess what: this is combined with opentrack the ideal replacement. It “just works” and is easy to set up. Fair pricing. 5 stars. Thank you, John."

Head Tracker

Really good app, pairs perfectly with Opentrack. I’m gonna rate this 5 stars even though I wish it came with the ability to brighten my screen as a form of flash so the camera has a better time tracking my head. I find that using it in a darkened room is hard because the camera has trouble staying with your head but other than that it works really good.

As good as Track IR for hundreds less

Saw this app mentioned on a forum and thought I would try it out since I just dropped $200 on Track IR and wasn't as impressed with it as I was 10 years ago with FSX. After setting up some curves on open track tried this out in MSFS 2020 and was very impressed. Will be returning my track IR and using this whenever I fly.

This is awesome with all my sims

I’ve use this in American Truck Sim, Train Simulator and Microsoft Flight Sim with my iPad Pro 11 Inch. This is just great! Even on my low end laptop it moves mostly smoothly which is awesome. The performance is very good and it’s great how you can test it out, then if you enjoyed it like I did, buy for only $2! A great deal and a great software.
