+## Native iPhone WebGPU sample
+
+`ProGPU.Samples.iOS` is a thin native host for the same `ProGPU.Samples` gallery used by desktop and browser. It renders directly into a physical-pixel `CAMetalLayer` through a Metal-only `wgpu-native` XCFramework and the existing Silk.NET WebGPU API. It has no MAUI, Uno, `WKWebView`, or JavaScript rendering dependency.
+
+```bash
+./eng/build-wgpu-native-ios.sh
+dotnet build src/ProGPU.Samples.iOS/ProGPU.Samples.iOS.csproj \
+  -c Debug -r iossimulator-arm64
+```
+
+The iOS-specific solution, native build details, ABI pin, architecture research, simulator commands, physical-device guidance, and current limitations are in [`docs/ios.md`](docs/ios.md).
+
+## Native Android WebGPU sample
+
+`ProGPU.Samples.Android` is the corresponding thin .NET Android host for the
+shared gallery. It renders directly to an `ANativeWindow`-backed WebGPU surface
+through Vulkan, with no browser, Android `Canvas`, MAUI, Uno, or readback path.
+
+```bash
+export ANDROID_NDK_ROOT=/absolute/path/to/android-sdk/ndk/your-version
+./eng/build-wgpu-native-android.sh arm64
+dotnet build src/ProGPU.Samples.Android/ProGPU.Samples.Android.csproj \
+  -c Debug -f net10.0-android
+```
+
+The Android architecture, exact native ABI pin, ARM64/x64 build lane, AOT
+publishing guidance, input/IME/inset/storage contracts, clean-room research,
+and device validation gates are in [`docs/android.md`](docs/android.md).

 ## Browser WebGPU sample
 
-The gallery is split into a shared `ProGPU.Samples` library and thin `ProGPU.Samples.Desktop` and `ProGPU.Samples.Browser` hosts. The browser host publishes with the .NET WebAssembly SDK, negotiates WebGPU capabilities, sends aligned binary command packets directly from WASM memory, and passes embedded WGSL unchanged to `GPUDevice.createShaderModule`.
