I just set up a donation page, you can find it on the github repo page, on the right. But please keep in mind that for now I have to finish my exams so you may have to wait a bit for new features. Also, any feedback and suggestions for improvement are appreciated especially since you work in the field.
I implemented the algorithm myself and although I don't have much experience with mobile apps programming I think that converting it to other programming languages or adapting it for other frameworks would be fairly easy. The real problem is the 3D rendering which is done using WPF 3D (Windows only), so I would need to completely rework it.
If you're going to rework it, perhaps consider making it a web app? Wrap it in Electron for desktop use, I bet there's something similar for iOS / Android.
That'd make it available as both a dedicated app for power users, and an (ad-supported) variant for occasional use.
Moving to Avalonia from WPF should be relatively straightforward (except, possibly, the WPF 3D part), and Avalonia is capable of targeting mobile platforms (even though it really is desktop-first, when compared to Uno or MAUI). As a bonus it will run on macOS and Linux too.
