+## How do I write a mobile app with Svelte?
+
+While most mobile apps are written without using JavaScript, if you'd like to leverage your existing Svelte components and knowledge of Svelte when building mobile apps, you can turn a [SvelteKit SPA](https://kit.svelte.dev/docs/single-page-apps) into a mobile app with [Tauri](https://v2.tauri.app/start/frontend/sveltekit/) or [Capacitor](https://capacitorjs.com/solution/svelte). Mobile features like the camera, geolocation, and push notifications are available via plugins for both platforms.

+Svelte Native was an option available for Svelte 4, but note that Svelte 5 does not currently support it. Svelte Native lets you write NativeScript apps using Svelte components that contain [NativeScript UI components](https://docs.nativescript.org/ui/) rather than DOM elements, which may be familiar for users coming from React Native.

 ## Can I tell Svelte not to remove my unused styles?
 
 No. Svelte removes the styles from the component and warns you about them in order to prevent issues that would otherwise arise.
