SmoothTrack 2.0 uses the head and eye tracking 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." - Charlie Hall, 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). Additionally, since version 2, your eyes are also optionally tracked and will nudge the camera based on where you're glancing on screen! - 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 simple camera gestures, you can shift your perspective in-game. Also, if you want, you can store views (say, a copilot angle, or a cockpit closeup) as Quick Views for easy access later. 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! Email and Discord support is provided if there are any issues (or if you have any ideas for new features!). ## Key features - 6DoF head tracking - Optional eye tracking - No extra hardware required - Works with FreeTrack/TrackIR games - Customizable view presets - Exaggerated head movements for control ## Chart rankings - #151 in Top Paid · Action (US App Store) - #164 in Top Paid · Simulation (US App Store) ## What do users think of SmoothTrack?

Literally plug and play, very easy USB setup with zero latency. 10/10. All for 15 dollars! ### 1/5 — Overpriced trash *2026-05-14, version 2.01* Doesn’t work ### 5/5 — 1:1 with vr after tweaks *2026-05-09, version 2.01* whoever made this app i finally tweaked everything and it looks like my old vr footage now. this is worth way more than 15 bucks i was skeptical at first oh my days. airpod feature is a game changer ### 5/5 — Awesome *2026-04-20, version 2.01* I got my brother into dcs and I needed a second head tracking salutation - didn’t want to buy track ir again and now I don’t have to! This is amazing thanks to the developers ### 5/5 — Simply Amazing *2026-01-02* Such a great application, it works smoother than neural net no need to have your CPU do more processing when summing, all the processing is done on your iOS device. Such great work from the developer, and look forward to the future features. ### 1/5 — Super hard to install *2025-12-25, version 2.01* Like the idea but super frustrating and confusing to install can’t get it to work waste of $15 for me! ### 1/5 — After 6 weeks of effort….. *2025-12-09, version 2.01* …..this just doesn’t work. I went to forums, YouTube and followed instructions to the letter without fail. I tried contacting support and no response. This was anything but easy to set up. In fact it’s pretty complicated and not at all intuitive or user friendly. What a waste of money. ### 5/5 — Best option for head tracking *2025-12-03, version 2.01* I previously used TrackIR, but this works better as it doesn’t require any LED lights or hat clips (which I keep loosing!). ### 5/5 — Amazing App *2025-11-07* Best low cost headtracking and the creator is very accessible ### 5/5 — Smoothtrack *2025-11-05, version 2.01* Great for flight sims, i use it in arma, dcs, and war thunder to great effect. Cheap, effective, greatly enhanced abilities ## Frequently asked questions about SmoothTrack ### What does SmoothTrack do? SmoothTrack uses your phone's camera to track your head and eye movements, translating them into in-game camera control for PC simulation games. It offers 6 degrees of freedom for a more immersive experience without requiring any extra hardware like VR headsets or specialized trackers. ### What games are compatible with SmoothTrack? Any game that supports the FreeTrack or TrackIR protocol will work with SmoothTrack. This includes popular titles such as Microsoft Flight Simulator, DCS World, Elite: Dangerous, and Euro Truck Simulator 2, among many others. ### Do I need to buy any extra equipment to use SmoothTrack? No, absolutely not. SmoothTrack is designed to work solely with the AR capabilities of your smartphone. You do not need any headsets, external cameras, or other accessories to use it. ### How does the head tracking work? The app uses your phone's camera to monitor your head's position and orientation. These movements are then translated into in-game camera adjustments, with movements slightly exaggerated to allow for precise control with subtle head gestures. ### Can I save specific camera views? Yes, you can store custom views, such as a copilot perspective or a close-up of the cockpit, as 'Quick Views'. This allows for easy and quick access to these pre-set camera angles during gameplay. ## Version history (last 5 releases) ### 2.01 — 2025-10-25 2.01 - New App Clip for trying out a simplified version of SmoothTrack with yaw axis tracking! - Fixed QuickViews not persisting between app launches - Fixed eye tracking settings not persisting between app launches - Fixed AirPods Pro mode to work whether or not tracking was set to on. Added a button to show the AirPods Pro mode capability. 2.0 was a HUGE update of SmoothTrack: * Brand new and improved UI, rewritten from the ground up to be 93% less ugly! * Added eye tracking capabilities for nudging the view when glancing around! Activate eye tracking by tapping the eye button, and set up eye tracking sensitivity in the settings. * You can now easily create camera offsets with camera control gestures: panning with one, two, or three fingers on the screen. * Easily save, choose, and delete offset quick views right on the main screen. I really hope you enjoy SmoothTrack! If you do, you can support it by leaving an App Store review and by spreading the word to your sim communities!

Thanks! ### 1.10 — 2024-05-28 FIXED: Restored AirPods Pro functionality missing in previous version. ### 1.09 — 2024-01-27 v1.09: Bug fix for an issue in which data would still be sent to OpenTrack during the calibration phase, causing a "drift" to occur during this phase. v1.08: TWO MAJOR NEW FEATURES: - New "120 FPS" mode which utilizes a higher scanning rate as well as some math magic to increase the tracking speed especially noticeable for those of you with higher frame rates in your games. - New "AirPods Pro" mode which will utilize AirPods Pro 3DOF head *direction* data (note: direction, not position). You can optionally combine this with the face tracking for 6DOF. Using this mode has a few potential advantages: - If you're on iPad, unlike AR tracking, AirPods Pro tracking will continue working even if SmoothTrack is used as a sidebar app! - You can have head direction correctly tracking in completely dark environments - You can leave face tracking entirely off if you want to save battery - For some scenarios (especially slower devices), AirPods data should be more precise and lower latency! ### 1.08 — 2024-01-05 TWO MAJOR NEW FEATURES IN THIS VERSION: - New "120 FPS" mode which utilizes a higher scanning rate as well as some math magic to increase the tracking speed especially noticeable for those of you with higher frame rates in your games. - New "AirPods Pro" mode which will utilize AirPods Pro 3DOF head *direction* data (note: direction, not position).
