This app allows using your phone as a head tracking device for games on your PC. Works with games which support FreeTrack 2.0 protocol but can also connect directly with Opentrack. Many flight or racing simulation games support head tracking. HeadTrack on your phone can be your head tracking device, no additional hardware is required. HeadTrack tracks your head movement and rotation which is sent to your games. The HeadTrack app on your phone supports Gyroscope or Camera as input. The Gyroscope input has very little latency which makes it good for quick movements. The Camera input supports full 6DoF tracking. Supported Inputs • HeadTrack (recommended) - Available for iOS with Gyroscope or Camera. • Opentrack App - Connect any app which is compatible with Opentrack. • Live Link App - Another alternative iOS app with camera input Supported Outputs • FreeTrack (recommended / Windows only) - Head tracking data is sent to games which support FreeTrack 2.0. This should work with most games which support head trackers. • Opentrack - Head tracking data is sent to Opentrack on this PC. This is useful if you already have Opentrack set up. • FlightGear - Plugin for FlightGear • X-Plane - Plugin for X-Plane 9+ Supported Games Most games which support head tracking should work with HeadTrack. Some games we can confirm are working: Arma 3, BeamNG.drive, FlightGear, X-Plane. In your game, look into the settings if there is any support for FreeTrack or similar head tracking devices. If there is any input or output you would like to see added, let us know!

Verdict
The clearest difference is update cadence: TriFAn at fortnightly against HeadTrack's every 5 weeks. TriFAn also leads on iOS requirement (9.3 vs 14.1). HeadTrack's advantage is device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
