Designed to integrate with the X-Plane flight simulator, AirFMC provides an interface layer to your favourite flight management system and allows you to have a remote, portable and beautiful CDU, leaving your screen free for enjoying the scenic routes. Flying with an FMC is good but have you ever thought how annoying it is to have to look for the small keys on a virtual cockpit and click on them with a mouse to get something done? What if you could now do it wirelessly with your fingertips using an iPad's big screen? And what if you could use just one App for all your favourite planes? AirFMC does just this; brings the CDU of your favourite planes to the tip of your fingers. In its current release we are proud to support the following list of planes and FMC systems: For X-Plane: - The x737 Boeing 737-800 from EADT using x737FMC - The UFMC from Javier Cortes - The CRJ-200 from Javier Rollon - The Boeing 777 Worldliner by FlightFactor - The Boeing 757 Professional by FlightFactor - The X-FMC freeware project and all the planes in which it runs - The QPAC A320 v2 - The Boeing 767 from VMAX - The A320NEO from JAR Design - The Boeing 737 Classifc from IXEG / X-Aviation - The Boeing 737-800 modified by Zibo - The Airbus A350 XWB Advanced from FlightFactor - The Airbus A319, A321 and A340 from ToLiss - The A330 from JAR Design - The MD80 from Rotate - The Boeing 737-700 and 737-900 Ultimate - The A320 from Flight Factor - The Hot Start CL650 - And lastly the X-Plane airliner FMC shipped with default planes FOr MSFS 2020: - PMDG 737 NG3 Family of Planes Please note, AirFMC is not an FMC in its own right. It does not have "intelligence" so to say, it does not manage routes nor flight performance parameters. At least, not yet! What it does is, it connects to planes that already have these systems and provides an interface surface to their CDUs. AirFMC works in conjunction with X-Plane and MSF2020 (on selected planes) through the use of a plugin which must be installed in the flight simulator and it requires a TCP/IP network connecting this app to a flight simulator.

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!).

Verdict

The call

The clearest difference is rating: SmoothTrack at 4.7 against AirFMC's 4.2. SmoothTrack also leads on price ($14.99 vs $19.99) and ratings volume (250 vs 15). AirFMC's advantage is update cadence (every 6 weeks vs every 4 months) and device support (4 vs 2). On ads, in-app purchases and monetization model there is nothing between them.
