Building a mobile and desktop version of your app will be challenging unless it's a very simple application or unless you accept that they likely will share very, very little code or design. The form factors and UI models are so different. Even doing this with the web is extremely challenging, again unless the application is relatively simple. Creative apps in particular do not "port" between these two contexts very well at all, whether you use the web or not. Yes, such things exist, but it is very debatable whether the desktop users of e.g. Figma have much use for the same thing in a mobile browser.
