There's an ongoing effort in the LiveView Native project: https://github.com/liveview-native/live_view_native

That seems out of scope for LiveView itself. You could of course use LiveView from a WebView shell. There is a project for bundling Elixir in an app as well. Not sure it is active? But they don't usually rot too bad. https://github.com/elixir-desktop/desktop

DockYard has built out LiveView Native which does a wild React Native style based on the LiveView server-rendered model.
