X Plane Steam Gauges Free is a free-to-use simulation game developed by Crosscheck Software and is available for Android 4.1 and above. The game is a demo version of the X Plane Steam Gauges Pro, which includes more instruments and features.

To use X Plane Steam Gauges Free, you need to have a working version of X-Plane or newer and connect your computer running X-Plane and your Android device to the same network. Once connected, the app will automatically configure and connect to X-Plane without any intervention from you. The demo version includes only the airspeed indicator and altitude indicator.

If you encounter any connection problems, the app provides a list of solutions to try, such as disabling the smart network switch on your Android device, making sure your Android device is connected to the same subnet as your computer, disabling firewalls on both your X-Plane computer and your Android device, and checking your router settings so that they are not set to filter out multicast traffic.

Overall, X Plane Steam Gauges Free is a good option for those who want to test the app before purchasing the full version, and for those who only need the airspeed indicator and altitude indicator. For those who want more features, the X Plane Steam Gauges Pro version is recommended.
