There have been cross platform API and tools forever and they all suck and you end up not taking advantage of the platform and features.

Java Swing, Electron, QT, React Native, etc.

If you are going to create a “native” app that doesn’t take advantage of the platform features, you might as well just use the web.

Besides, it’s always a leaky abstraction that forces you to have some type of escape hatch to take advantage of subtleties of the platform.
