A number of default aircraft configuration files are included but you can easily make your own and download them to your iFMS through iTunes. The FMS display and functionality simulates the "Boeing style" Flight Management System accurately. Apart from all the standard flight planning and tracking functionality, all the more complex functions such as hold programming, custom waypoint programming by coordinates, heading/distance calculation or waypoints radial/intersection calculation and abeam route waypoint calculations are available as well, along with much, much more. iFMS also includes an LNAV/VNAV engine which will control your aircraft's autopilot to fly the programmed LNAV/VNAV route. iFMS uses Wi-Fi to connect to your favorite Flight Simulator over your local network, alternatively iFMS can also use the device GPS (if present) as a data source, you can be a passenger in the car and practice your FMS programming skills. Be aware though, iFMS cannot be used for real world aviation navigation as this is strictly against the terms of use of this product. iFMS can be configured for use with almost any of your favorite Flight Simulator's standard aircraft and most add-on aircraft, a number of default aircraft are included but you can easily make your own on your computer and transfer them to iFMS through iTunes.

AirTrack is an application designed to integrate with flight simulators in real time over a local area network, providing remote flight display and control through glass cockpit instruments, as well as control over some of the simulation variables. It replicates instruments and panels found on real planes using devices such as tablets and computers. With the aid of a plugin in the simulator, flight data is exchanged over the local network and displayed on the Mac, iPad and iPhone apps. Likewise actions on these are propagated back to the simulator and allow for its remote control. But if this isn't enough, AirTrack can also use your device's built-in GPS, Accelerometer and Gyro to determine your current movements and attitude and the Internet to download real weather to simulate an aircraft's sensors. Turn your car trip into a flight experience by getting information about your instant position, heading and surrounding waypoints. See yourself in an EFIS style navigation display / primary flight display or plan your multi-leg trip with the built in flight planner which gives you real-time information about your waypoints, how far they are and how long it will take you to reach them.

Verdict
The clearest difference is review sentiment: AirTrack NG at 100% against iFMS's 46%. AirTrack NG also leads on rating (5.0 vs 3.1) and update cadence (weekly vs every 4 weeks). iFMS's advantage is price ($15.99 vs $24.99) and in-app purchases (none vs 5). On ads, monetization model and device support there is nothing between them.
