+# 📱 Vaultix Mobile — Dev Builds
+
+This guide covers how to generate development builds for the Vaultix mobile app and distribute them for internal testing.
+
+---
+
+## Prerequisites
+
+- Node.js 18+
+- pnpm (`npm install -g pnpm`)
+- [Expo CLI](https://docs.expo.dev/get-started/installation/) (`pnpm add -g expo-cli`)
+- [EAS CLI](https://docs.expo.dev/eas/) (`pnpm add -g eas-cli`)
+- Physical device or simulator/emulator
+- Apple Developer account (iOS) or Expo account (Android)
+
+---
+
+## Option 1: EAS Build (Recommended)
+
+EAS (Expo Application Services) builds the app in the cloud and is the easiest way to produce shareable dev builds.
+
+### 1. Install EAS CLI
+
+```bash
+pnpm add -g eas-cli
+```
+
+### 2. Log in to Expo
+
+```bash
+eas login
+```
+
+### 3. Configure EAS
+
+Create an `eas.json` file at the **root of the mobile app** (`apps/mobile/eas.json`):
+
+```json
+{
+  "cli": {
+    "version": ">= 3.0.0"
+  },
+  "build": {
+    "development": {
+      "developmentClient": true,
+      "distribution": "internal",
+      "channel": "development"
+    },
+    "preview": {
+      "distribution": "internal",
+      "channel": "preview"
+    },
+    "production": {}
+  },
+  "submit": {
+    "production": {}
+  }
+}
+```
+
+### 4. Build for Development
+
+```bash
+# From apps/mobile
+eas build --profile development --platform all
+```
+
+**Platform-specific builds:**
+
+```bash
+# iOS only
+eas build --profile development --platform ios
+
+# Android only
+eas build --profile development --platform android
+```
+
+### 5. What Happens
+
+- EAS uploads your project to Expo's servers
+- Builds the native app (iOS IPA / Android APK/AAB)
+- Downloads the build artifact or sends it to your registered device(s)
+
+### 6. Install the Build
+
+- **iOS**: Install via the link EAS provides (TestFlight-like) or download the `.ipa` and install via Xcode
+- **Android**: Download the `.apk` or `.aab` and install directly on device
+
+### 7. Start the Dev Server
+
+After installing the dev build on your device/emulator:
+
+```bash
+cd apps/mobile
+npx expo start --dev-client
+```
+
+This starts the Metro bundler. Open the app on your device (scan QR code or press `a` for Android / `i` for iOS).
+
+---
+
+## Option 2: Local Dev Build (Expo Dev Client)
+
+Use this when you want to build locally without cloud infrastructure.
+
+### iOS (requires macOS + Xcode)
+
+```bash
+# Generate the native iOS project
+npx expo prebuild --platform ios
+
+# Open in Xcode and build
+cd apps/mobile/ios
+pod install
+open Vaultix.xcworkspace
+# Select a simulator or connected device, then Build & Run (Cmd+R)
+```
+
+### Android (requires Android Studio)
+
+```bash
+# Generate the native Android project
+npx expo prebuild --platform android
+
+# Open in Android Studio
+cd apps/mobile/android
+open -a "Android Studio" .
+
+# Build APK
+cd apps/mobile/android
+./gradlew assembleDebug
+```
+
+---
+
+## Option 3: Expo Go (Quick Testing)
+
+For quickest feedback without a dev build, use [Expo Go](https://expo.dev/go). Note that custom native modules won't work in Expo Go if you ever add native dependencies beyond what Expo provides out of the box.
+
+```bash
+cd apps/mobile
+npx expo start
+```
+
+Then scan the QR code with **Expo Go** on your device.
+
+---
+
+## Internal Distribution
+
+### iOS — TestFlight via EAS Submit
+
+```bash
+# First, ensure you have an App Store Connect API key or Apple ID credentials
+eas submit --platform ios --profile production
+```
+
+### Android — Internal Testing Track
+
+```bash
+eas submit --platform android --profile production
+```
+
+Or share the `.apk` directly via a link (if using EAS Build with internal distribution).
+
+---
+
+## Running Checks Before Build
+
+Always run these checks before building to catch issues early:
+
+```bash
+# From apps/mobile
+
+# 1. Lint
+pnpm lint
+
+# 2. Type check
+pnpm type-check
+
+# 3. Run tests
+pnpm test
+
+# 4. All three combined
+pnpm validate
+```
+
+---
+
+## Troubleshooting
+
+### Build fails at "pod install"
+
+```bash
+cd apps/mobile/ios
+pod deintegrate
+pod install --repo-update
+```
+
+### Metro bundler can't resolve modules
+
+```bash
+cd apps/mobile
+pnpm start --clear
+# or
+npx expo start -c
+```
+
+### EAS Build fails
+
+- Check logs in the EAS dashboard
+- Ensure `eas.json` has the correct profile
+- Verify your Expo account has sufficient build credits
+- Try building for a single platform first
+
+### Dev build crashes on launch
+
+- Ensure the Metro dev server is running (`npx expo start --dev-client`)
+- Check for native module mismatches in `package.json`
+- Clear the dev client cache:
+  ```bash
+  npx expo start -c
+  ```
+

+---
+
+## Tips for Testers
+
+- **Reset state**: Clear app data or reinstall to test fresh-start scenarios.
+- **Network simulation**: Toggle airplane mode to verify error states.
+- **Backend**: Ensure the backend is running (`cd apps/backend && pnpm start:dev`) and seeded with test data.
+- **Reporting bugs**: Include screen name, step number, expected vs actual result, and a screenshot/video if possible.
