You are probably not solving the same problems many other people are facing.

Many such applications are accessible on the web, often with the exact UI. They may even have a mobile/iPad version. They may be big enough that they have a design system that needs to be applied to in every UI (including company website). Building C++ code on all platforms and running all the tests may be too expensive. The list goes on.

I just started prototyping a mobile version of my app (which shares the code as my desktop app) and the result looks promising (still work-in-progress tho).

Offering a web app is indeed not trivial. Maybe Qt WebAssembly will be a viable option if I can optimize the binary and users wouldn't mind first long load time (and then the app should be cached for instant load). Or maybe I could build a read-only web app using web technology.

Currently, my focus is building a good native application, and I think most of my users care about that. But in the future, I can see how a web app could be useful for more users. One thing I would like to built is a web browser that could load both QML and HTML files (using regular web engine), so I could simply deploy my app by serving my QML files without the binary over the internet.
