I spent a while working on a digital painting app in Unity. UIToolkit is not complete, but it is pretty good for web-like UI, and you can leverage existing knowledge of HTML/CSS layout. With some tweaks you tell Unity to only redraw the screen on demand, which is better for battery life. My experience is that Unity could be pretty good for cross-platform semi-graphical app development. Except that Unity dev is miserable (slow, never-ending compilation, bad docs, constant bugs, glacial update pace, broken Linux editor, etc etc etc).
