FsHub is a free cloud service that provides virtual pilot and airline flight tracking and performance monitoring for Microsoft Flight Simulator 2020, X-Plane, Prepar3D, FSX, FSX:SE and FS2004! That is the official saying, and I would add it is wonderfull free service. Also offers many “achievements” to give you more reasons to soar the virtual skies and visit places you maybe did not know about existing.
