My App definition was a bit too narrow maybe, games too tend to be multi platform. I think that’s possible when the App and user interaction model is completely custom - like shooting zombies or drawing 3D shapes. That's also party why browsers can't replace every app(the browsers have it's own opinion about the UI and interactions), the other reasons are performance and access limitations.
