I'm not sure how feasible a Linux version is. I'm not using toolkits that make cross platform development easy or simple. Those toolkits often have drawbacks in that they don't always perform (or look) like a native app on each OS. There are also a lot of different permissions to handle on each OS. For example, Windows 10 is very restrictive when it comes to what directories applications are allowed to access (even more so than Android), and in Android 6.0+, many permissions have to be requested from users now.

On Android, MobileSheetsPro is written in Java, and the user interfaces are designed using XML. For Windows 10, it's all written in C# as a UWP app using XAML for the user interfaces. I don't see how either of those can easily be ported over to Linux where I'd probably have to write everything in either Mono (for C#) or C++ using something like Qt for the user interfaces. It would most likely be another rewrite for Linux, and almost no one has requested a Linux version of the app. I have gotten a few requests for Linux versions of the companion app, but I've actually gotten far more requests for a Mac version of the companion app (or an iOS version of MobileSheetsPro).
