A post titled “Sibling Rivalry” by Ben was published on the official X-Plane developer blog. The article explains the relationship between the X-Plane 10 desktop and mobile versions. The summary of the content is as follows:

Without the revenue from the X-Plane 9 mobile version, Laminar Research could not have initiated the development of the X-Plane 10 desktop version. In the past, due to limited resources, Laminar Research only had the capacity to develop one product at a time. Now, with more developers finally hired, work can proceed simultaneously on both the X-Plane 10 desktop and mobile versions, representing the “two fronts” approach. Advanced and powerful mobile devices have also made code sharing between the two products possible, such as in terms of OpenGL, and there is no longer a significant gap in software performance. Additionally, the Android version of X-Plane 10 Mobile is currently under development.
