SmoothTrack: Head Tracker 4+

Head tracking for sim games

John Goering

    • $9.99



SmoothTrack uses the AR capabilities of your phone to provide the simplest and best head tracker for 6 degrees-of-freedom head movements in your sim games.


"The best new controller on the market will only set you back $9.99. It's a smartphone app called SmoothTrack." - Polygon

Customer reviews:

"SmoothTrack just works. Less than 5 minutes to install, setup and fly. Love not being tethered to my desk! 5 stars!!"
"This worked perfectly and way better than expected! Totally enhanced my experience with MFS 2020!"

It's a near magical experience to seamlessly slightly move your head and have your game perspective immediately play along (the movements in the game are exaggerated so that you only have to make slight movements of your head to control the camera).

- Simply lean forward to get a closer look at your Flight Simulator cockpit!
- Look a bit up to see the overhead panel of your A320!
- Simply shift your head a bit to the right to see the direction of the space station you're approaching in Elite: Dangerous!
- Look a bit left before a hard left turn in Euro Truck Simulator 2!

No headset or extra equipment of any kind is required! Simply set up your device so that it can see your face. Using the on-screen controls, you can shift your perspective in-game.

Your head movements are slightly exaggerated which enables you to look out of a cockpit side window with just a slight movement of your head to the left.

Any game that supports the FreeTrack or TrackIR protocol will work with this, including:

- Microsoft Flight Simulator
- Microsoft FSX
- DCS World
- Elite: Dangerous
- IL2: Sturmovik
- Euro Truck Simulator 2
- Kerbal Space Program
- ...and many, many others!

INSTRUCTIONS (included in the app):

1. On your computer, install and run the latest version of the free program "OpenTrack". It is available on GitHub at
2. In OpenTrack, as "Input source", choose "UDP over network". As Output, choose "Freetrack 2.0 Enhanced", as its sub-type "Both".
3. Make sure the UDP port OpenTrack is using is open both on your firewall and router.
4. Find the IP address of your PC by running 'ipconfig' in a Command Line - look for "IPv4 Address".
5. Now, in SmoothTrack, set up your IP address and port in the settings
6. Press "Start" in OpenTrack
7. Tap Play here in SmoothTrack and you should see the OpenTrack octopus move around, which means any game that supports TrackIR will now be supporting your head tracking! If the octopus is not moving, then check Troubleshooting for more detailed instructions.

Email support is provided if there are any issues (or if you have any ideas for new features!).

Who knew flying could get any more fun?

I have been a pilot, both fixed-wing and rotary-wing, in an Arma 3 unit for a while now and my biggest gripe with flying was the lack of visual information without using a head tracker. I use a joystick and to free look without this app, you need to take your hands off the stick to go to the keyboard and free look. This is extremely dangerous as you lose all of your fine controls just to take a look at where you need to land. I’ve looked into getting TrackIr but those options seemed too pricey to get in my opinion. This app is at the perfect value however. $10 is such a good price for what you get. While still rough around the edges, (not of the fault of the devs but from limitations of the system being from a phone) I think it does the job well. The customization both in the app and in Opentrack helps alleviate some of those issues. Overall I think any pilot should give this option a shot if they are interested with a head tracking system and don’t already own TrackIr or other alternatives.

Works Great For Microsoft Flight Sim

This is the first experience I have had with using head tracking of any kind, but it works fantastic. Right out of the box the range of movement that is detected is actually very impressive.

Looking around feels great and there's no perceivable input latency. Without messing with any in app settings I can lean close, look down, and access all of my aircraft's systems. This is huge. No longer do I have to take 15mins to keybind stuff for every aircraft that I fly. It is liberating, allows for more flying, less keybinding, and has seriously improved my skill in sim flying.
The setup wasn't too bad either, my only advice would be to make sure you can port forward with your networking setup (this is a must unless you're going to use the desktop app standalone with a webcam). It is astounding that it works with Microsoft Flight Sim with zero setup in the sim itself. I cannot speak enough praise for this app.

One of the best add ins for flight sim

As a former rw pilot of 22 years and avid flight summer in the past after a 10 year hiatus I broke down and got a new computer and msfs 2020. When setting up with latest hardware and some ancient the sim still didn’t feel real. As a past user of tracker ir I thought I would give this app a try. After a challenging setup mostly due to windows 11 idiot proofing thanks to the great help files included with the app got it up and running. I am not exaggerating that the realism of the sim went up about 80%! As a former user of tracker ir this does it all with no wires and no headset. With an iPhone stand I have my phone charging on a great almost unseen place to the left of my velocity yoke and this thing just works-perfectly. One of the best most useful add ins for flight simulator! Extremely happy!
